Yu (Ю, ю) is a letter of the Cyrillic alphabet, representing either the combination /ju/ (a so-called iotated vowel) or /u/ after a palatalized consonant. Apart from the form I-O, in early Slavonic manuscripts the letter appears also in a mirrored form O-I. It is this form that is probably original, precisely displaying the Greek combination omicron-iota (οι). At the time the Greek alphabet was adapted to the Slavonic language (giving rise to the Cyrillic alphabet), this denoted Close front rounded vowel /y/ in educated Greek speech. This digraphic representation of /y/ was so basic for speakers of Greek that the simple letter upsilon (υ) representing the same sound came to be called υ ψιλόν (y psilon) "simple" υ in contrast to "complex" οι. Probably in analogy to the 'iotated' letters Ѥ, ІА, Ѩ and Ѭ, which fulfilled similar functions in Slavonic, this OI ligature was soon mirrored to the modern form ю.
