y tilde

Latin Small Letter Y with Tilde · U+1EF9

ỹ is the lowercase y with a tilde, the small wave above the letter. Vietnamese writes its six tones as diacritics on vowels, and the tilde marks the ngã (glottalized rising) tone, so ỹ is that tone’s form of the vowel y. Its capital form is Ỹ (U+1EF8). Click the tile to copy ỹ, then paste it anywhere with Ctrl+V (Windows), Cmd+V (Mac) or a long-press → Paste on a phone.
