In the [[Germanic languages]], '''weak verbs''' are by far the largest group of verbs, and are therefore often regarded as the norm (the [[regular and irregular verbs|regular verbs]]). They are distinguished from the [[Germanic strong verb]]s by the fact that their past tense form is marked by an inflection containing a {{IPA|/t/}}, {{IPA|/d/}}, or {{IPA|/ð/}} sound (as in English ''I walk~I walked'') rather than by changing the verb's root vowel (as in English ''I rise~I rose'').

Whereas the strong verbs are the oldest group of verbs in Germanic, originating in [[Proto-Indo-European language|Indo-European]], the weak verbs arose as an innovation in [[Proto-Germanic language|Proto-Germanic]]. Originally the weak verbs consisted of new verbs coined from pre-existing nouns (for example the noun ''name'' was turned into the verb ''to name''), or coined from strong verbs to express the sense of causing the action denoted by that strong verb (for example the strong verb ''to rise'' was turned into the weak verb ''to raise'').

However, over time, the weak verbs have become the normal form of verbs in all Germanic languages, with most strong verbs being reassigned to the weak class. For example, in Old English the verb ''to lock'' ({{lang|ang|lūcan}}) was strong (present tense {{lang|ang|ic lūce}} 'I lock', past tense {{lang|ang|ic lēac}} 'I locked'), but has now become weak. This transition is ongoing. For example, the English verb ''to cleave'' currently exists in both a conservative strong form (past tense ''I clove'') and an innovative weak form (past tense ''I cleaved~I cleft'').

==General description==
In Germanic languages, weak verbs form their [[preterite]]s and [[past participle]]s by means of a [[Dental consonant|dental]] [[Affix|suffix]], an inflection that contains a {{IPA|/t/}} or {{IPA|/d/}} sound or similar. (For comparative purposes, they will be referred to as a dental, but in some of the languages, including most varieties of English, {{IPA|/t/}} and {{IPA|/d/}} are [[alveolar consonant|alveolar]] instead.) In all Germanic languages, the preterite and past participle forms of weak verbs are formed from the same stem.

Historically, the pronunciation of the suffix in the vast majority of [[Regular verb|weak verbs]] (all four classes) was {{IPA|[ð]}} but, in most sources discussing [[Proto-Germanic]], it is spelled {{angbr|d}} by convention. In the [[West Germanic languages]], the [[suffix]] [[Fortition|hardened]] to {{IPA|[d]}}, but it remained a [[fricative]] in the other early [[Germanic languages]] ([[Gothic language|Gothic]] and often in [[Old Norse]]).

In the [[English language]], the dental is a {{IPAc-en|d}} after a [[voiced consonant]] (''loved'') or [[vowel]] (''laid''), a {{IPAc-en|t}} after a [[voiceless consonant]] (''laughed''), and {{IPAc-en|ɪ|d}} after the [[Dental consonant|dentals]]/alveolars {{IPAc-en|t}} and {{IPAc-en|d}} themselves, but English uses the suffix spelling {{angbr|ed}} regardless of pronunciation, with the exception of a few verbs with irregular spellings.{{efn |Often also somewhat irregular past tenses as well: ''make'' {{IPAc-en|m|eɪ|k}}, made {{IPAc-en|m|eɪ|d}} (from earlier ''maked''); ''say'' {{IPAc-en|s|eɪ}}, ''said'' {{IPAc-en|s|ɛ|d}}, ({{abbr|<|derived from}} [[Middle English|Μid.Εngl.]] {{wikt-lang|enm|saie}}, {{wikt-lang|enm|saied}}); {{wikt-lang|en|sleep}} {{IPAc-en|s|l|iː|p}}, {{wikt-lang|en|slept}} {{IPAc-en|s|l|ɛ|p|t}}, and so on.}}

In [[Dutch language|Dutch]], {{IPA|/t/}} and {{IPA|/d/}} are distributed as in English provided there is a following [[vowel]]. When there is no following vowel, [[final devoicing|terminal devoicing]] leads to the universal {{IPA|/t/}}. Nevertheless, Dutch still distinguishes between the [[spelling]]s in {{angbr|d}} and {{angbr|t}} even in final position: see the [['t kofschip]] rule.

In [[Afrikaans]], which descends from Dutch, the [[past tense]] has fallen out of use altogether, and the past participle is marked only with the prefix {{lang|af|ge-}}. Therefore, the suffix has disappeared along with the forms that originally contained it.

In [[German language|German]] the dental is always {{IPA|/t/}} and always spelled {{angbr|t}} because of the third phase of the [[High German consonant shift]] (d→t).

In [[Low German]], the dental ending of the preterite tense was originally {{IPA|/d/}} or {{IPA|/t/}}, according to the stem of the verb. However the ending has fallen out in pronunciation, starting in the 17th century when the preterite was written with the ending {{lang|de|-er}} representing the sound {{IPA|[ɐ]}}, which was already the last remnant of the former ''-de'' and ''-te'' endings of Middle Low German. Now, the only Low German verbs that still show a remnant of a dental ending are {{lang|nds|leggen}}, which has the preterite {{lang|nds|leed}}, and the verb {{lang|nds|hebben}}, which has {{lang|nds|harr}} with old ''r''-ending from the Middle Low German dental.

In [[Icelandic language|Icelandic]], the dental was originally a voiced dental fricative {{IPA|/ð/}}. It is preserved as such after vowels, voiced fricatives, and {{IPA|/r/}} but has been hardened to a stop {{IPA|/d/}} after nasals and {{IPA|/l/}}. It and has been devoiced to {{IPA|/t/}} after voiceless consonants and in some other cases (in most Old Norse texts, the alternation is already found in heavy roots, but the light ones preserve {{IPA|/ð/}}). Furthermore, the voicing contrast between {{IPA|/d/}} and {{IPA|/t/}} has been replaced in modern Icelandic by an [[Aspirated consonant|aspiration]] contrast, which may not be realized phonetically in all the relevant positions.

The situation of early [[Norwegian language|Norwegian]] was similar to Icelandic, but intervocalic {{IPA|/ð/}} eventually disappeared. In the verbs in which it remains, the dental is {{IPA|/t/}} or {{IPA|/d/}}, depending on conjugation class and [[Norwegian dialects|dialect]]. It is spelled accordingly. In [[Nynorsk]], it can be different in the preterite and the past participle.

[[Swedish language|Swedish]] has a similar situation to that of Norwegian, but the dental is retained in the spelling, even between vowels. Some informal spellings indicate a lost dental, such as in {{lang|sv|sa}} ("said") from the standard spelling {{lang|sv|sade}}.

==Classes of verbs==
In [[Proto-Germanic]], there were seven types of weak verbs, five of which were common.  However, they are normally grouped into four classes, based on the conjugational system of Gothic.

===Class I verbs===
Class I verbs actually consist of three classes in [[Proto-Germanic]]:

====Class I, subclass (i)====
A small class of verbs had no suffix in the present, and no suffix in the past (other than the '''-d-''' or '''-t-''' of all weak verbs).  This class had only three members:

#{{lang|gem-x-proto|'''*bringaną'''}} "to bring", past tense {{lang|gem-x-proto|'''*branht-'''}}.  This verb was continued as such in all the descendants, although an alternate stem {{lang|gem-x-proto|'''*brangij-'''}} occasionally appeared in some of the [[West Germanic languages]] (e.g., [[Old English]] {{lang|ang|brenġan}}).
#{{lang|gem-x-proto|'''*brūkaną'''}} "to use", past tense {{lang|gem-x-proto|'''*brūht-'''}}.  This verb tended to move into other classes.  For example, in Gothic this verb moved into subclass (ii) of Class I ({{lang|got-Latn|'''brūkjan'''}}, past {{lang|got-Latn|'''brūhta'''}}), whereas in Old English it became a Class II strong verb ({{lang|ang|brūcan}}, past tense {{lang|ang|brēac}} ← {{lang|ang|*brauk}}).
#{{lang|gem-x-proto| '''*būaną'''}} "to dwell", past tense {{lang|gem-x-proto| '''*būd-'''}}.  This verb continued as such in most descendants but became a Class III weak verb {{lang|got-Latn|'''bauan'''}} in Gothic.

====Class I, subclass (ii)====
A small class of verbs had the suffix '''-j-''' in the present and no suffix in the past.  This class had only five members in Proto-Germanic:

#{{lang|gem-x-proto|'''*bugjaną'''}} "to buy," past tense {{lang|gem-x-proto|'''*buht-'''}}
#{{lang|gem-x-proto|'''*sōkijaną'''}} "to seek," past tense {{lang|gem-x-proto|'''*sōht-'''}} (given a regularized subclass (iii) past {{lang|got-Latn|'''sōkida'''}} in Gothic)
#{{lang|gem-x-proto|'''*þankijaną'''}} "to think," past tense {{lang|gem-x-proto|'''*þanht-'''}}
#{{lang|gem-x-proto|'''*þunkijaną'''}} "to seem," past tense {{lang|gem-x-proto|'''*þunht-'''}}
#{{lang|gem-x-proto|'''*wurkijaną'''}} "to work," past tense {{lang|gem-x-proto|'''*wurht-'''}}

Verbs of this class were said to undergo [[rückumlaut]] ("reverse umlaut") in the past, since the [[Germanic umlaut|umlaut]] occurring in the present (triggered by the '''-j-''') is undone or "reversed" in the past (due to the lack of the umlaut-triggering stem '''-i-''' of subclass [iii]), leading to a non-umlauted vowel in the past.

These verbs also have consonant and vowel alternations between present and past that are due to regular sound changes but result in strikingly different forms in the historical Germanic languages (e.g., ''think'', past tense ''thought'').  Specifically:
*There is an alternation between '''-k-''' or '''-g-''' in the present and '''-h-''' in the past, caused by the '''-t-''' of the past-tense suffix.  Prior to the operation of [[Grimm's Law]], the stem consonant was '''-g-''' or '''-gʰ-'''.  Before '''-t-''', the consonant was devoiced to '''-k-''' by [[assimilation (linguistics)|assimilation]] and then became '''-h-''' by [[Grimm's Law]]. This alternation is sometimes called [[Primärberührung]].
*'''-n-''' before '''-h-''' disappeared after nasalizing the previous vowel.  When the '''-n-''' disappeared, the vowel was lengthened by the process of [[compensatory lengthening]].
*'''-u-''' was lowered to '''-o-''' in the past tense due to [[a-mutation]], since the following vowel was always non-high.

The class remained small in Gothic, but expanded significantly in the other languages:

*In Old Norse, all short-stem verbs (those with a short vowel followed by at most one consonant, or a long vowel followed by no consonant) appeared to move into this class, as indicated by the fact that no umlaut occurs in the past, as would be caused by a suffix '''-i-'''.  However, this may have been due to a regular sound change that eliminated unstressed, nonfinal short vowels coming after a short stem before the operation of umlaut.
*In [[Old High German]], short-stem verbs ending in '''-zz (-tz), -pf, -ck''' (Proto-Germanic root ending in '''*-t, -p,''' or '''-k'''), and optionally those in '''-ll''', join this class.  For example, {{lang|goh|'''zellen'''}} "to tell" < {{lang|goh|'''*taljan'''}}, past tense {{lang|goh|'''zalta, zelita'''}}.  A number of long-stem verbs also join this class, like {{lang|goh|'''brennen'''}} "to burn," past tense {{lang|goh|'''branta'''}}; {{lang|goh|'''wenten'''}} "to turn," past tense {{lang|goh|'''wanta'''}}.
*In Old English and the other northern [[West Germanic languages]], a number of verbs ending in '''-(c)c-''' and '''-ll-''' joined the class, including the following Old English verbs:
:*{{lang|ang|cweccan}} "to shake" < {{lang|ang|*kwakjan}}, past tense {{lang|ang|cweahte}} < {{lang|ang|*kwaht-}}
:*{{lang|ang|dreccan}} "to afflict," past tense {{lang|ang|dreahte}}
:*{{lang|ang|læccan}} "to seize" (based on earlier {{lang|ang|*lǣcan}}?), past tense {{lang|ang|lǣhte}}
:*{{lang|ang|leccan}} "to moisten," past tense {{lang|ang|leahte}}
:*{{lang|ang|rǣcan}} "to reach" < {{lang|ang|*raikjan}}, past tense {{lang|ang|rǣhte, rāhte}} < {{lang|ang|*raiht-}}
:*{{lang|ang|reccan}} "to narrate," past tense {{lang|ang|reahte}}
:*{{lang|ang|reccan}} "to care for" (based on earlier {{lang|ang|*rēcan}}?), past tense {{lang|ang|rōhte}}
:*{{lang|ang|tǣcan}} "to teach," past tense {{lang|ang|tǣhte, tāhte}}
:*{{lang|ang|streccan}} "to stretch," past tense {{lang|ang|streahte}}
:*{{lang|ang|þeccan}} "to cover," past tense {{lang|ang|þeahte}}
:*{{lang|ang|weccan}} "to awake," past tense {{lang|ang|weahte}}
:*{{lang|ang|cwellan}} "to kill" < {{lang|ang|*kwaljan}}, past tense {{lang|ang|cwealde}} < {{lang|ang|*kwald}}
:*{{lang|ang|dwellan}} "to dwell," past tense {{lang|ang|dwealde}}
:*{{lang|ang|sellan}} "to give, sell," past tense {{lang|ang|sealde}}
:*{{lang|ang|stellan}} "to place," past tense {{lang|ang|stealde}}
:*{{lang|ang|tellan}} "to tell," past tense {{lang|ang|tealde}}

In Late Old English, further verbs in '''-can''' were drawn into this class by analogy, but with umlaut maintained, e.g., {{lang|ang|bepǣcan}} "to deceive", past tense {{lang|ang|bepǣhte}}, earlier {{lang|ang|bepǣcte}}, or {{lang|ang|wleccan}} "to warm," past tense {{lang|ang|wlehte}}, earlier {{lang|ang|wlecede}}.  At the same time, verbs in '''-ccan''' were modified to follow the same pattern, as in the new past tense form {{lang|ang|cwehte}} alongside earlier {{lang|ang|cweahte}}.

====Class I, subclass (iii)====
A large class of verbs had the suffix '''-j-''' in the present and '''-i-''' in the past, for example, Gothic {{lang|got-Latn|'''satjan'''}} "to set" (Old English {{lang|ang|settan}}) and '''sandjan''' "to send" (Old English {{lang|ang|sendan}}).  As shown in the Old English cognates:
*The '''-j-''' produced [[Germanic umlaut|umlaut]] of the stem vowel in languages other than Gothic.
*The '''-j-''' caused [[West Germanic gemination]] in the West Germanic languages in short-stem verbs ending in a consonant other than '''-r'''.
*The '''-j-''' resulted in [[Palatalization (sound change)|palatalization]] of preceding [[velar consonant]]s in Old English.
*The '''-j-''' remained in Gothic and [[Old Saxon]], but disappeared in the other languages: In long-stem verbs in Old Norse, and in all verbs except those in '''-r''' in the remaining West Germanic languages. (In [[Old High German]], it deflected '''*-jan''' into '''*-jen''' before disappearing, leaving the suffix '''-en'''. This phenomenon, which resembles the usual umlaut of '''a''' in syllables ''preceding'' '''j''', is nevertheless distinct and must have happened later, as the missing '''j''' also caused umlaut.)

This class was split into two subclasses in all the Old Germanic languages, one consisting of short-stem verbs and one of long-stem verbs.  The distinction between the two was originally due to [[Sievers' Law]], and was extended due to changes such as [[West Germanic gemination]], which affected short-stem but not long-stem verbs.  The West Germanic languages had a third subclass consisting of short-stem verbs ending in '''-r''' (e.g., Old English {{lang|ang|erian}} "to plow," {{lang|ang|nerian}} "to save," {{lang|ang|styrian}} "to stir"), due to [[West Germanic gemination]] and subsequent loss of '''-j-''' not taking place.

The following is a cross-language paradigm of a short-stem Class I verb {{lang|gem-x-proto|'''*gramjaną'''}} "to anger" (Gothic {{lang|got-Latn|'''gramjan'''}}, Old Norse {{lang|non|'''gremja'''}}, [[Old High German]] {{lang|goh|'''gremmen'''}}, [[Old Saxon]] {{lang|osx|'''*gremmian'''}}, Old English {{lang|ang|gremman}}, [[Old Frisian]] {{lang|ofs|'''*gremma'''}}).  Note that the Old Saxon and Old Frisian verbs given here are unattested, almost certainly due to the small nature of the respective corpora.

===Class II verbs===
Class II verbs were formed with a suffix '''-ō-'''.  In the northern West Germanic languages, an alternative extended suffix '''-ōja-''' sometimes appears in the non-past forms, e.g., the Old English infinitive {{lang|ang|'''-ian''' < '''*-ōjan'''}}.

The following is a cross-language paradigm of {{lang|gem-x-proto|'''*laþōną'''}} "to invite" (Gothic {{lang|got-Latn|'''laþōn'''}}, Old Norse {{lang|non|'''laða'''}}, Old High German {{lang|goh|'''ladōn, lathōn'''}}, Old Saxon {{lang|osx|'''lathian [-ōjan]'''}}, '''ladian [-ōjan]''', Old English {{lang|ang|'''laþian'''}}, Old Frisian {{lang|ofs|'''lathia'''}}).

===Class III verbs===
What is known as "Class III" was actually two separate classes in Proto-Germanic:
*A class of verbs with [[stative verb|stative]] semantics (i.e., denoting a state rather than an action), formed with a present suffix that was either '''*-ai-''' or '''*-ja-''', and no suffix in the past.
*A class of verbs with [[factitive]] semantics (i.e., with the meaning "make X" where X is an adjective or noun, e.g., "renew, enslave"), formed with a suffix that was either '''*-ai-''' or '''*-ā-''', and a suffix '''*-a-''' in the past.

The histories of this class in the various Germanic languages are quite varied:
*Old High German combined both into a single class and generalized '''*-ai-''' (appearing as '''-ē-''' through regular sound change) to all forms of the present and past.
*Gothic combined both into a single class, keeping the '''*-ai-/-ā-''' alternation of the factitives in the present, generalizing the alternation to the statives as well, and borrowing '''*-ai-''' as the past suffix.
*Old Norse for the most part combined both into a single class in the same fashion as Gothic; however, two relic stative verbs ({{lang|non|'''segja'''}} "to say" and {{lang|non|'''þegja'''}} "to be silent") preserve the stative suffixes in both present and past, and a third verb ({{lang|non|'''hafa'''}} "to have") is a mixture of the two, with factitive suffixes in the present indicative plural and imperative and stative suffixes in the present indicative singular and past participle (elsewhere, the two types have fallen together).
*The other (i.e., northern) West Germanic languages have only small numbers of Class III verbs—but they consistently follow the stative paradigm, unlike the three languages above.

An example is the stative verb reconstructed as [[Proto-Germanic]] {{lang|gem-x-proto|'''*habjaną'''}} "to have", past indicative third-person singular {{lang|gem-x-proto|'''habdē'''}}:
*Old English {{lang|ang|'''hebban'''}} < {{lang|ang|'''*habjan'''}}, past, third-person singular {{lang|ang|'''hæfde'''}} — derived entirely through regular sound changes.
*Old High German {{lang|goh|'''habēn'''}}, past, third person singular {{lang|goh|'''habēta'''}} — derived through analogical spread of suffix '''-ē-'''.
*Gothic {{lang|got-Latn|'''haban'''}}, past, third-person singular {{lang|got-Latn|'''habáida'''}} — derived through various analogical changes.
*Old Norse {{lang|non|'''hafa'''}}, past, third-person {{lang|non|'''hafði'''}} — partly regular, partly analogical.

Only four stative verbs survive as Class III verbs in the [[North Sea Germanic|northern West Germanic]] languages (i.e., Old English, Old Saxon, Old Frisian and [[Old Low Franconian]]):
*{{lang|gem-x-proto|'''*sagjaną'''}} "to say"
*{{lang|gem-x-proto|'''*libjaną'''}} "to live"
*{{lang|gem-x-proto|'''*habjaną'''}} "to hold, have"
*{{lang|gem-x-proto|'''*hugjaną'''}} "to think"

However, there are five more verbs that appear as Class III verbs in Old High German, Gothic, and/or Old Norse that also have remnants of the stative conjugation in one or more northern West Germanic languages:
*{{lang|gem-x-proto|'''*þagjaną'''}} "to be silent"
*{{lang|gem-x-proto|'''*siljaną'''}} "to be silent"
*{{lang|gem-x-proto|'''*þuljaną'''}} "to endure" (normally Class II {{lang|ang|'''þolian'''}} in Old English, but compare archaic umlauted infinitive {{lang|ang|'''-þoelġe'''}}; Class III in Old Norse {{lang|non|'''þola'''}})
*{{lang|gem-x-proto|'''*fijaną'''}} "to hate"
*{{lang|gem-x-proto|'''*hatjaną'''}} "to hate" (normally Class II {{lang|ang|'''hatian'''}} in Old English, but compare umlauted nominalized present participle {{lang|ang|'''hettend'''}} "enemy"; Class III in Gothic {{lang|got-Latn|'''hatan'''}})

===Class IV verbs===
Class IV verbs were formed with a suffix '''-nan''', e.g., Gothic {{lang|got-Latn|'''fullnan'''}} "to become full".  The present tense was conjugated as a strong verb, for example, Gothic {{lang|got-Latn|'''fullna, fullnis, fullniþ'''}}, etc.  The past tense was conjugated with suffix '''-nō-''', e.g., Gothic {{lang|got-Latn|'''fullnōda, fullnōdēs'''}}, etc.  This class vanished in other Germanic languages; however, a significant number of cognate verbs appear as Class II verbs in Old Norse and as Class III verbs in Old High German.  This class has [[Finite Verb|fientive]] semantics, that is, "[[Inchoative verb|become X]]," where X is an adjective or a past participle of a verb.

*Examples of deadjectival Class IV verbs in Gothic are {{lang|got-Latn|'''ga-blindnan'''}} "to become blind" ('''blinds''' "blind"), {{lang|got-Latn|'''ga-háilnan'''}} "to become whole" ({{lang|got-Latn|'''háils'''}} "whole").  
*Examples of deverbal Class IV verbs in Gothic are {{lang|got-Latn|'''fra-lusnan'''}} "to perish" ({{lang|got-Latn|'''fra-liusan'''}} "to destroy"), {{lang|got-Latn|'''ga-þaúrsnan'''}} "to dry up, wither away" ({{lang|got-Latn|'''ga-þaírsan'''}} "to wither"), {{lang|got-Latn|'''mikilnan'''}} "to be magnified" ({{lang|got-Latn|'''mikiljan'''}} "to magnify"), {{lang|got-Latn|'''us-háuhnan'''}} "to be exalted" ({{lang|got-Latn|'''us-háuhjan'''}} "to exalt").

Note that the last two are deverbal even though the underlying root is adjectival because they are formed to other verbs (which are in turn formed from adjectives).

The vast majority of Class IV verbs appear to be deverbal.  Class IV verbs derived from weak verbs keep the same stem form as the underlying weak verb.  However, class IV verbs derived from strong verbs adopt the ablaut of the past participle, for example:
*{{lang|got-Latn|'''dis-skritnan'''}} "to be torn to pieces" (Class I {{lang|got-Latn|'''dis-skreitan'''}} "to tear to pieces")
*{{lang|got-Latn|'''us-gutnan'''}} "to be poured out" (Class II {{lang|got-Latn|'''giutan'''}} "to pour")
*{{lang|got-Latn|'''and-bundnan'''}} "to become unbound" (Class III {{lang|got-Latn|'''and-bindan'''}} "to unbind")
*{{lang|got-Latn|'''dis-taúrnan'''}} "to be torn asunder, burst asunder" (Class IV {{lang|got-Latn|'''dis-taíran'''}} "to tear asunder, burst")
*{{lang|got-Latn|'''ufar-hafnan'''}} "to be exalted" (Class VI {{lang|got-Latn|'''ufar-hafjan'''}} "to exalt")
*{{lang|got-Latn|'''bi-auknan'''}} "to abound, become larger" (Class VII {{lang|got-Latn|'''bi-aukan'''}} "to increase, add to").

==Modern languages==
In the modern languages, the various classes have mostly been leveled into a single productive class.  Icelandic, Norwegian and Frisian have retained two productive classes of weak verbs. (In Frisian, in addition to the class with '''-de''', there is a class of '''je-''' verbs, where the dental suffix has dropped, i.e., '''-je''' < '''-iad'''.) [[Swiss German]] also has two types of weak verbs, descended from Class I and Classes II and III, respectively, of Old High German weak verbs and marked with '''-t''' and '''-et''', respectively, in the [[past participle]].<ref>{{cite book |first=Rudolf Ernst |last=Keller |year=1961 |title=German dialects: phonology and morphology, with selected texts |publisher=Manchester University Press}}</ref>

In the history of English, the following changes happened:

#Most Class III verbs were moved into Class II prior to the historical period of Old English.
#The remaining four Class III verbs moved into Class I or Class II late in Old English.
#Throughout the Middle English period, Class I verbs gradually moved into Class II.

In modern English, only one productive weak paradigm remains, derived from Class II.  A number of Class I verbs still persist, for example:

*From Old English subclass (i): '''bring (brought)'''
*From Old English subclass (ii) or analogously: '''buy (bought)'''; '''catch (caught)'''; '''seek (sought)'''; '''sell (sold)'''; '''teach (taught)'''; '''tell (told)'''; '''think (thought)'''; '''work (wrought)''' [''obsolescent'']
*From Old English subclass (iii) or analogously: '''bend (bent)'''; '''bet (bet)'''; '''breed (bred)'''; '''build (built)'''; '''cast (cast)'''; '''cost (cost)'''; '''creep (crept)'''; '''cut (cut)'''; '''deal (dealt)'''; '''dream (dreamt)'''; '''feed (fed)'''; '''flee (fled)'''; '''hear (heard)'''; '''hit (hit)'''; '''hurt (hurt)'''; '''keep (kept)'''; '''kneel (knelt)'''; '''knit (knit)'''; '''lay (laid)'''; '''lead (led)'''; '''leap (leapt)'''; '''leave (left)'''; '''lend (lent)'''; '''light (lit)'''; '''lose (lost)'''; '''mean (meant)'''; '''meet (met)'''; '''put (put)'''; '''read (read)'''; '''rend (rent)''' [''obsolescent'']; '''send (sent)'''; '''set (set)'''; '''shed (shed)'''; '''shoot (shot)'''; '''shut (shut)'''; '''sleep (slept)'''; '''speed (sped)'''; '''spend (spent)'''; '''spill (spilt)'''; '''split (split)'''; '''spread (spread)'''; '''sweep (swept)'''; '''thrust (thrust)'''; '''wed (wed)'''; '''weep (wept)'''; as well as a few others
*From Old English Class III verbs: '''have (had)'''; '''say (said)'''

As the previous list shows, although there is only one productive class of weak verbs, there are plenty of "irregular" weak verbs that do not follow the paradigm of this class.  Furthermore, the regular paradigm in English is not unitary, but in fact is divided into subclasses in both the written and spoken language, although in different ways:
*In the written language, before the past-tense suffix '''-ed''', short-stem verbs double the final consonant (e.g., '''dip [dipped]'''), while a '''-y''' following a consonant becomes '''-i-''' (e.g., '''carry [carried]''').
*In the spoken language, the past-tense suffix '''-ed''' is variously pronounced {{IPA|/t/, /d/}}, or {{IPA|/ɪd, əd/}} depending on the preceding consonant.

Both of these characteristics occur in a similar fashion in most or all the modern Germanic languages.  In modern German, for example, descendants of the original subclass (ii) of Class I are still irregular (e.g., {{lang|de|'''denken [dachte]'''}} "to think", {{lang|de|'''brennen [brannte]'''}} "to burn"), and subclasses of the productive verb paradigm are formed by verbs ending in '''-eln''' or '''-ern''' and in '''-ten''' or '''-den''', among others.

===Modern paradigms===
One of the regular weak verb conjugations is as follows.

==Weak and strong verbs==
Weak verbs should be contrasted with [[Germanic strong verb|strong verbs]], which form their past tenses by means of ''[[Indo-European ablaut|ablaut]]'' (vowel gradation: ''sing - sang - sung''). Most verbs in the early stages of the Germanic languages were strong. However, as the ablaut system is no longer productive except in rare cases of analogy. Almost all new verbs in Germanic languages are weak, and the majority of the original strong verbs have become weak by analogy.

===Strong to weak transformations===
As an example of the rather common process of originally strong verbs becoming weak, we may consider the development from the Old English strong verb {{lang|ang|scūfan}} to modern English ''shove'':
* {{lang|ang|scūfan scēaf scofen}} (strong class 2)
* ''shove shoved shoved''
Many hundreds of weak verbs in contemporary English go back to Old English strong verbs.

In some cases, a verb has become weak in the preterite but not in the participle and may be thought of as "semi-strong" (not a technical term). Dutch has a number of examples:
*{{lang|nl|wassen waste gewassen}} ("to wash")
*{{lang|nl|lachen lachte gelachen}} ("to laugh")

An example in English is:
*''sow sowed sown'' (strong class 7 with weak preterite)

Often, the old strong participle may survive as an adjective long after it has been replaced with a weak form in verbal constructions. The English adjective ''molten'' is an old strong participle of ''melt'', which is now a purely weak verb with the participle ''melted''. The participle {{lang|de|gebacken}} of the German verb {{lang|de|backen}} (to bake), is gradually being replaced by {{lang|de|gebackt}}, but the adjective is always {{lang|de|gebacken}} (baked).

===Weak to strong transformations===
The reverse process is very rare and can also be partial, producing "semi-strong" verbs as in ''show showed shown'' (originally a weak verb with its participle modelled on ''sown'').

Weak verbs that develop strong forms are often unstable. A typical example is German {{lang|de|fragen}} ("to ask"), which is historically weak and is still weak in standard German. However, for a time in the 18th century, the forms {{lang|de|fragen, frug, gefragen}} by analogy with, for example, {{lang|de|tragen}} ("to carry") were also considered acceptable in the standard. They survive today (along with a present tense {{lang|de|frägt}}) in the [[Rhinelandic regiolect]] and underlying dialects. In Dutch, {{lang|nl|vragen}} (idem) has developed the new strong past {{lang|nl|vroeg}} in place of an expected ''**vraagde'', while retaining a weak past participle {{lang|nl|gevraagd}} (though some dialects do have {{lang|nl|gevrogen}}).

==Origins==
The weak conjugation of verbs is an innovation of [[Proto-Germanic]] (unlike the older strong verbs, the basis of which goes back to [[Proto-Indo-European language|Proto-Indo-European]]). While primary verbs (those inherited from PIE) already had an ablaut-based perfect form that was the basis of the Germanic strong preterite. Secondary verbs (those derived from other forms after the break-up of PIE) had to form a preterite otherwise, which necessitated the creation of the weak conjugation.

===Denominative derivation===
The vast majority of weak verbs are secondary, or derived. The two main types of derived verbs were denominative and deverbative. A denominative verb is one that has been created out of a noun. The denominative in Indo-European and early Germanic was formed by adding an ablauting [[Vowel stems|thematic]] *-y{{frac|é|ó}}- suffix to a noun or adjective.  This created verbs such as Gothic {{lang|got-Latn|namnjan}} 'to name'.

===Causative verbs===
A significant subclass of Class I weak verbs are (deverbal) [[causative verb]]s. They are formed in a way that reflects a direct inheritance from the PIE causative class of verbs. PIE causatives were formed by adding an accented affix ''-éy-'' to the ''o''-grade of a non-derived verb.  In Proto-Germanic,  causatives are formed by adding a suffix ''-j/ij-'' (the reflex of PIE ''-éy-'') to the past-tense ablaut (mostly with the reflex of PIE ''o''-grade) of a strong verb (the reflex of PIE non-derived verbs), with [[Verner's Law]] voicing applied (the reflex of the PIE accent on the ''-éy-'' suffix):

*{{lang|gem-x-proto|*bītaną}} (I) "to bite" → {{lang|gem-x-proto|*baitijaną}} "to bridle, yoke, restrain," i.e., "to make bite down"
*{{lang|gem-x-proto|*rīsaną}} (I) "to rise" → {{lang|gem-x-proto|*raizijaną}} "to raise," i.e., "to cause to rise"
*{{lang|gem-x-proto|*beuganą}} (II) "to bend" → {{lang|gem-x-proto|*baugijaną}} "to bend (transitive)"
*{{lang|gem-x-proto|*brinnaną}} (III) "to burn" → {{lang|gem-x-proto|*brannijaną}} "to burn (transitive)"
*{{lang|gem-x-proto|*frawerþaną}} (III) "to perish" → {{lang|gem-x-proto|*frawardijaną}} "to destroy," i.e., "to cause to perish"
*{{lang|gem-x-proto|*nesaną}} (V) "to survive" → {{lang|gem-x-proto|*nazjaną}} "to save," i.e., "to cause to survive"
*{{lang|gem-x-proto|*ligjaną}} (V) "to lie down" → {{lang|gem-x-proto|*lagjaną}} "to lay," i.e., "to cause to lie down"
*{{lang|gem-x-proto|*sitjaną}} (V) "to sit" → {{lang|gem-x-proto|*satjaną}} "to set, seat," i.e., "to cause to sit"
*{{lang|gem-x-proto|*faraną}} (VI) "to travel, go"  → {{lang|gem-x-proto|*fōrijaną}} "to lead, bring," i.e., "to cause to go"
*{{lang|gem-x-proto|*faraną}} (VI) "to travel, go"  → {{lang|gem-x-proto|*farjaną}} "to carry across," i.e., "to cause to travel" (an archaic instance of the ''o''-grade ablaut used despite the differing past-tense ablaut)
*{{lang|gem-x-proto|*grētaną}} (VII) "to weep" → {{lang|gem-x-proto|*grōtijaną}} "to cause to weep"
*{{lang|gem-x-proto|*lais}} (I, preterite-present) "(s)he knows"  → {{lang|gem-x-proto|*laizijaną}} "to teach," i.e., "to cause to know"

Essentially, all verbs formed this way were conjugated as Class I weak verbs.

That method of forming causative verbs is no longer productive in the modern Germanic languages, but many relics remain. For example:
*The original strong verb ''fall fell fallen'' has a related weak verb ''fell felled felled'', which means "to cause (a tree) to fall"
*Strong ''sit sat sat'' and ''lie lay lain'' are matched with weak ''set set set'' and ''lay laid laid'', meaning "to cause something to sit" or "lie" respectively.

In some cases, phonological or semantic developments make the pairs difficult to recognise. For example:
*''Rear'' is the regular phonological development of Proto-Germanic {{lang|gem-x-proto|*raizijaną}} given in the above list, but the connection between ''rise'' and ''rear'' is no longer obvious. The word ''raise'' also ultimately defines from ''*raizijaną'', but only via borrowing from Old Norse. The connection is perhaps made more obvious by noting that ''to rear a child'' is essentially synonymous with ''to raise a child''.
*''Drench'' was originally the causative of ''drink'', but the modern meaning of "drench" ("to cause to get wet") is no longer similar to "cause to drink". 
*Similarly, German strong {{lang|de|leiden litt gelitten}} ("to suffer") has the derived weak verb {{lang|de|leiten}} ("to lead"), which makes sense when one realises that {{lang|de|leiden}} originally meant "walk, go" and came to its present meaning through the idea of "undergoing" suffering.

===Other types===
There are primary verbs that date to Indo-European that took a weak conjugation because they were unable to take a perfect, including verbs that had zero grade of the root in the present and so were unable to show the ablaut distinction necessary for a strong preterite. That was the case with the Gothic verbs {{lang|got-Latn|waurkjan}} "to work, create," {{lang|got-Latn|bugjan}} "to buy," and {{lang|got-Latn|sokjan}} "to seek."

Preterite-present verbs are primary verbs in which the PIE present was lost, and the perfect was given a present meaning. They needed a new past tense, which followed the weak pattern.

Most borrowings from other languages into Germanic were weak. However, this was not always the case: for example, {{wikt-lang|gem-pro|*skrībaną|i=no}} 'to write' from Latin {{wikt-lang|la|scrībō|i=no}}.

===Origin of dental suffix===
The origin of the dental suffix is uncertain. Perhaps the most commonly held theory is that it evolved out of a [[Periphrasis|periphrastic]] construction with the verb {{wikt-lang|gem-pro|*dōną}} ''to do'': Germanic *{{lang|gem-x-proto|lubō-dē-}} ("love-did") > {{lang|gem-x-proto|*lubōdē-}} > Old English {{lang|ang|lufode}} > ''loved'' or *{{lang|gem-x-proto|salbō-dē-}} ("salve-did", i.e., "put salve") > *{{lang|gem-x-proto|salbōdē-}} > Old English {{lang|ang|sealfode}} > ''salved''. That would be analogous to [[do-support]] in modern English: ''I did love'', ''I did salve''.

The common PIE root {{lang|ine-x-proto|*dʰeh₁-}} meaning 'do' was a root [[aorist]] and so did not take a perfect. However, it took a reduplicating present. The imperfect of the root, which filled in the simple past in Germanic, is probably the origin of the dental suffix.

|}

That view is not without objections:{{citation needed|date=September 2017}}
* Germanic has long -ē- in the plural, which cannot directly reflect the Proto-Indo-European situation.
* Reduplication is only in the Gothic plural, not in the singular.

The objections are sometimes answered as follows:{{citation needed|date=September 2017}}
* There might have been a refashioning according to cases like {{lang|gem-x-proto|gēbun,}} namely, {{lang|gem-x-proto|*gegbun > gēbun: *dedun → dēdun}}.
* Reduplication only in the plural can easily be explained by [[haplology]] in Proto-Germanic ({{lang|gem-x-proto|*dede-}} being reduced to {{lang|gem-x-proto|*de-}}) for the singular, with a later development of haplology for the plural in non-[[East Germanic languages]].

Another theory is that it came from a past participle ending, a final *''-daz'' from PIE *''-tos'' (compare Latin {{lang|la|amatus}}), with personal endings added to it at a later stage. That theory, however, is also disputed because of its inability to explain all the facts.

According to Hill (2010), the endings, which in the singular do not show reduplication in any Germanic language, continue the PIE subjunctive of the root aorist.{{cn |date=December 2024}}

==Other meanings==
The term "weak verb" was originally coined by [[Jacob Grimm]], who only applied it to Germanic philology. However, the term is sometimes applied to other language groups to designate phenomena that are not really analogous. For example, [[Hebrew]] ''irregular'' verbs are sometimes called weak verbs because one of their radicals is weak. See [[weak inflection]].
