Ot (Cyrillic)

Russian textbook, printed by 
Ivan Fyodorov in 1574. This page features the Cyrillic alphabet.
 
Ot (Ѿ ѿ; italics: Ѿ ѿ) is a letter of the early Cyrillic alphabet. Though it originated as a ligature of the letters Omega (Ѡ ѡ) and Te (Т т), it functions as a discrete letter of the alphabet, placed between х and ц.[1] This can be seen in the first printed Cyrillic abecedarium (illustrated), and continues in modern usage.[2]
Ot is used in Church Slavonic to represent the preposition отъ 'from' and prefix от-.  It does not stand for this sequence of letters in any other context, nor can the sequence от be substituted for it where it does occur. It is used with a similar purpose in mediaeval manuscripts of other Slavonic languages written with the Cyrillic alphabet. In printed books ѿ is often used in preference to (ѡ҃) for the numeral 800.
