Russian

Letter

ѳ • (f) (lower case, upper case Ѳ)

1. (obsolete) The letter fita (Russian фита́ (fitá)) or ѳита́ (fitá)). A consonantal letter intended to represent the Greek phoneme /θしーた/, which was approximated in Russian by /f/. Replaced by the letter ф (f) in the spelling reform of 1917.

Usage notes

• This letter was used in words of Greek origin in cases where Russian /f/ derived from Greek θしーた (th) rather than φふぁい (ph). For example, орѳогра́фія (orfográfija, “orthography”), Ѳивы (Fivy, “Thebes”), etc.
• In some words the pronunciation had changed to /t/ under French and German influence. These were accordingly replaced with т (t) instead of ф (f).
