R

R, or r, is the eighteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ar (pronounced Template:IPAc-en), plural ars.

The letter Template:Angbr is the eighth most common letter in English and the fourth-most common consonant, after Template:Angbr, Template:Angbr, and Template:Angbr.

Name

The name of the letter in Latin was (), following the pattern of other letters representing continuants, such as Template:Angbr, Template:Angbr, Template:Angbr, Template:Angbr, and Template:Angbr. This name is preserved in French and many other languages. In Middle English, the name of the letter changed from to , following a pattern exhibited in many other words such as farm (compare French ) and star (compare German ).

In Hiberno-English, the letter is called or , somewhat similar to oar, ore, orr.

The letter ⟨R⟩ is sometimes referred to as the 'canine letter', often rendered in English as the dog's letter. This Latin term referred to the Latin Template:Angbr that was trilled to sound like a growling dog, a spoken style referred to as 'dog voice' (e.g. in Spanish 'dog').

Antiquity

The word as written on the Sarcophagus of Lucius Cornelius Scipio Barbatus (280 BC) reveals the full development of the Latin Template:Angbr by that time; the letter Template:Angbr at the same time still retains its archaic shape distinguishing it from Greek or Old Italic rho.

The letter Template:Angbr is believed to derive ultimately from an image of a head, used in Semitic alphabets for the sound because the word for 'head' was rêš or similar in most Semitic languages. The word became the name of the letter, as an example of acrophony.

It developed into Greek Template:Angbr () and Latin Template:Angbr. The descending diagonal stroke develops as a graphic variant in some Western Greek alphabets (writing rho as ⟨File:Greek Rho 03.svg⟩), but it was not adopted in most Old Italic alphabets; most Old Italic alphabets show variants of their rho between a Template:Angbr and a Template:Angbr shape, but without the Western Greek descending stroke. Indeed, the oldest known forms of the Latin alphabet itself of the 7th to 6th centuries BC, in the Duenos and the Forum inscription, still write Template:Angbr using the Template:Angbr shape of the letter. The Lapis Satricanus inscription shows the form of the Latin alphabet around 500 BC. Here, the rounded, closing ⟨Π⟩ shape of the Template:Angbr and the Template:Angbr shape of the Template:Angbr have become difficult to distinguish. The descending stroke of the Latin letter Template:Angbr has fully developed by the 3rd century BC, as seen in the Tomb of the Scipios sarcophagus inscriptions of that era. From c. Template:Trim, the letter Template:Angbr would be written with its loop fully closed, assuming the shape formerly taken by Template:Angbr.

The minuscule form Template:Angbr developed through several variations on the capital form. Along with Latin minuscule writing in general, it developed ultimately from Roman cursive via the uncial script of Late Antiquity into the Carolingian minuscule of the 9th century.

In handwriting, it was common not to close the bottom of the loop but continue into the leg, saving an extra pen stroke. The loop-leg stroke shortened into the simple arc used in the Carolingian minuscule and until today.

A calligraphic minuscule Template:Angbr, known as r rotunda Template:Angbr, was used in the sequence Template:Angbr, bending the shape of the Template:Angbr to accommodate the bulge of the Template:Angbr as in Template:Angbr, as opposed to Template:Angbr. Later, the same variant was also used where Template:Angbr followed other lower case letters with a rounded loop towards the right, such as with Template:Angbr, Template:Angbr, Template:Angbr, as well as to write the geminate Template:Angbr as Template:Angbr. Use of r rotunda was mostly tied to blackletter typefaces, and the glyph fell out of use along with blackletter fonts in English language contexts mostly by the 18th century.

Insular script used a minuscule which retained two downward strokes, but which did not close the loop, known as the Insular r Template:Angbr; this variant survives in the Gaelic type popular in Ireland until the mid-20th century, but has become largely limited to a decorative function.

Use in writing systems

English

Template:Angbr represents a rhotic consonant in English, such as the alveolar approximant (most varieties), alveolar trill (some British varieties), or the retroflex approximant (some varieties in the United States, South West England and Dublin).

In non-rhotic accents, it is not pronounced in certain positions, but can affect the pronunciation of the vowel that precedes it.

R is the ninth most frequently used letter in the English language.

Other languages

Template:Angbr represents a rhotic consonant in many languages, as shown in the table below.

Alveolar trill	File:Alveolar trill.ogg	Standard Dutch, Estonian, Finnish, Galician, German in some dialects, Hungarian, Icelandic, Indonesian, Italian, Czech, Javanese, Lithuanian, Latvian, Latin, Norwegian mostly in the northwest, Polish, Portuguese (traditional form), Romanian, Russian, Scots, Slovak, Swedish more frequent in northern and western dialects, as well as in Finland Swedish; Sundanese, Ukrainian, Welsh; also Catalan, Spanish and Albanian Template:Angbr

Other languages may use the letter Template:Angbr in their alphabets (or Latin transliteration schemes) to represent rhotic consonants different from the alveolar trill. In Haitian Creole, it represents a sound so weak that it is often written interchangeably with Template:Angbr, e.g. 'Kweyol' for 'Kreyol'.

The doubled Template:Angbr represents a trilled in Albanian, Aragonese, Asturian, Basque, Catalan and Spanish.

Brazilian Portuguese has a great number of allophones of Template:IPAslink, such as Template:IPAblink, Template:IPAblink, Template:IPAblink, Template:IPAblink, Template:IPAblink, Template:IPAblink and Template:IPAblink. The latter three ones can be used only in certain contexts (Template:IPAblink and Template:IPAblink as Template:Angbr; Template:IPAblink in the syllable coda, as an allophone of Template:IPAslink according to the European Portuguese norm and Template:IPAslink according to the Brazilian Portuguese norm). Usually at least two of them are present in a single dialect, such as Rio de Janeiro's Template:IPAblink, Template:IPAblink, Template:IPAblink and, for a few speakers, Template:IPAblink.

Other systems

The International Phonetic Alphabet uses several variations of the letter to represent the different rhotic consonants; Template:Angbr IPA represents the alveolar trill.
