Fita (Ѳ, ѳ) is a letter of the early Cyrillic alphabet, escended from the Greek Theta. It was mainly used to write proper names derived from Greek. Since Russians would pronounce these names with an /f/ sound instead of the proper sound /θ/ (which is like English unvoiced "th") -- for example "Theodore" would be pronounced as "Fyodor" -- it was replaced in Russian by the letter Ef (Ф, ф) in 1918. In most other Slavic languages, Fita was pronounced /t/ and was replaced with Te, e.g. the Bulgarian and Serbian version of Theodore is Тодор or Теодор, romanized Todor or Teodor.
