U (Cyrillic)
U (У у; italics: У у) is a letter of the Cyrillic script. It commonly represents the close back rounded vowel /u/, somewhat like the pronunciation of ⟨oo⟩ in "boot". The forms of the Cyrillic letter U are similar to the lowercase of the Latin letter Y (Y y; Y y), but, as with most Cyrillic letters, the upper and lowercase forms are similar in shape differing mainly in size and vertical placement.
