Bopomofo Letter Ir

9/32

ㆨ marks a high, central vowel: the tongue is raised near the middle of the mouth, and the lips stay unrounded. It is used in Taiwanese phonetic notation, an extension of Mandarin Zhuyin (Bopomofo).

Text symbol

What ㆨ means

The tongue rises between the “ee” and “oo” positions.

Taiwanese Phonetic Symbols grew from Mandarin Bopomofo in 1946. Taiwan’s Ministry of Education included ㆨ in Fangyin, its Taiwanese pronunciation system, in 1998.

Some Quanzhou-leaning Taiwanese descriptions use it to distinguish this vowel from the “ee”-like and “oo”-like vowels. That distinction varies by dialect, so ㆨ is not a universal spelling across Taiwanese speech.
