O͘ o͘

O͘o͘ is one of the six Hokkien vowels as written in the Pe̍h-ōe-jī (POJ) orthography. It is pronounced Template:IPAblink, like the pronunciation of Template:Angbr in "law". Because Hokkien is a tonal language, the standard letter without a diacritic represents the vowel in the first and fourth tone with the fourth and eighth tone always only used in syllables with a syllable stop (i.e. Template:Angle bracket, Template:Angle bracket, Template:Angle bracket, Template:Angle bracket ), and the other six to eight possible tone categories require one of the following tonal symbols to be written above it:

• Ó͘ ó͘ (second tone) 《陰上／阴上》
• Ò͘ ò͘ (third tone) 《陰去／阴去》
• Ô͘ ô͘ (fifth tone) 《陽平／阳平》
• Ǒ͘ ǒ͘ (sixth tone, used in Quanzhou-descended dialects) 《陽上／阳上》
• Ō͘ ō͘ (seventh tone) 《陽去／阳去》
• O̍͘ o̍͘ (eighth tone) 《陽入／阳入》
• Ŏ͘ ŏ͘ / Ő͘ ő͘ (ninth tone, high rising in Taiwanese Hokkien)

History

File:First Phonetic Reader by Elias Longley.png

Carstairs Douglas's 1873 Chinese–English Dictionary of the Vernacular or Spoken Language of Amoy used a barred o with curl very similar to the one on the far left of the 4th row of letters from the top of this image to represent the sound that Pe̍h-ōe-jī (POJ) usually represented with O͘ o͘

The character was introduced by the Xiamen-based missionary Elihu Doty in the mid-nineteenth century, as a way to distinguish the Hokkien vowels and (the former becoming Template:Angle bracket). Since then it has become established in the Pe̍h-ōe-jī orthography, with only occasional deviations early in its usage – one example being Carstairs Douglas's 1873 Chinese–English Dictionary of the Vernacular or Spoken Language of Amoy, where he replaced the Template:Angle bracket with Template:Angle bracket (an o with a curl, similar to that of the English Phonotypic Alphabet), and a second example being Tan Siew Imm's 2016 dictionary of Penang Hokkien, where she replaced the Template:Angle bracket with Template:Angle bracket.

Computing

In the Unicode computer encoding, it is a normal Latin o followed by Template:Unichar, and is not to be confused with the Vietnamese Ơ. This letter is not well-supported by fonts and is often typed as either o· (using the interpunct), o• (using the bullet), o' (using the apostrophe), oo (as used in Tâi-lô for Taiwanese Hokkien and Wāpuro rōmaji for Japanese), or ou (as used in Wāpuro rōmaji for Japanese).
