U+0177 "ŷ" Latin Small Letter Y with Circumflex Unicode Character
Unicode Version 17.0
ŷ
U+0177 "ŷ" Latin Small Letter Y with Circumflex is a modified letter used in the Welsh language, where it represents a long stressed vowel sound, often appearing in words like "dŷ" meaning house or "hŷn" meaning older, and it is also occasionally used in transcriptions of other languages for phonetic precision. The circumflex diacritic indicates a distinct pronunciation from the plain letter Y, and its uppercase counterpart is U+0176 "Ŷ". In the Latin Extended-A block, this character supports proper orthography for Welsh and other linguistic contexts where vowel length or quality must be marked.
