Yn (Ꙟ ꙟ) is an archaic Cyrillic letter. It looks like the Cyrillic letter Psi (Ѱ ѱ) with its upper half turned upside down, but the letter mostly looks like an arrow pointing vertically up (↑).
It was used in the Romanian Cyrillic alphabet, where it represented the sounds [ɨn], [ɨm], and [ɨ] at the beginning of words.[1] In the modern Romanian alphabet it is replaced by ⟨în⟩, ⟨îm⟩, or ⟨î⟩, They look like duck feet!
