Izhitsa

Izhitsa (Ѵ, ѵ; Russian: И́жица) is a letter of the early Cyrillic alphabet and several later alphabets, usually the last in the row. It originates from the Greek letter ypsilon (Υ, υ) and was used in words and names derived from or via Greek, such as кѵрилъ (kürilǔ, 'Cyril') or флаѵии (flavii, 'Flavius'). It represented sounds /i/ or /v/ as normal letters и and в respectively. The Glagolitic alphabet has a corresponding letter with the same name izhitsa (Ⱛ, ⱛ). Also, izhitsa in its standard form or (mostly) in a tailed variant (similar to lowercase y) was a part of a digraph оѵ/оу representing sound /u/ (the digraph is known as Cyrillic letter Uk, and today's Cyrillic letter U originates from its simplified form).
