"ф" redirects here. For the very similar Greek letter, see Φ, φ or ϕ - Phi (Greek)

Ef (Ф, ф) is the twenty-second letter of the Cyrillic alphabet. It represents the consonant /f/ unless it is before a palatalizing vowel when it represents /fʲ/.

It was directly derived from the Greek letter phi (Φ). Additionally, it has replaced Fita (Ѳ) in the Russian version of the alphabet since 1918. Unlike phi, however, it is transliterated as f, not ph.

The Slavic languages practically do not have native words containing /f/; this sound, which did not exist in Proto-Indo-European, arose in Greek and Latin from PIE *bʰ (which yielded Slavic /b/) and in the Germanic languages from PIE *p (which remained unchanged in Slavic). The letter ф is, therefore, almost exclusively found in words of foreign origin, especially Greek (from both th and ph), Latin, French, German, English, and Turkic. Few native Slavic words with this letter (in different languages) are examples of onomatopoeia (like Russian verbs фукать, фыркать etc.) or reflect sporadic pronunciation shifts, for example пв /pv/ in Serbian уфати (from Church Slavonic уповати), and хв /xv/, or х /x/ in the Russian toponym Фили (from хилый).
