ℹ️ About
The Cyrillic Small Letter Ef (ф) is the lowercase version of the letter used to represent the voiceless labiodental fricative /f/. Historically, it is derived from the Greek letter Phi (Φ, φ). While it looks like a circle bisected by a vertical line, it is distinct from mathematical symbols or IPA characters.
⚠️ Note: Do not confuse with φ (Greek Small Letter Phi) or ø (Latin Small Letter O with Stroke).
