Main spellings (~99%)
⟨v⟩ ~85%
The letter ⟨v⟩ is extremely reliable — it almost always makes the /v/ sound.
⟨ve⟩ ~14%
Word-finally, ⟨v⟩ is almost always followed by a silent ⟨e⟩.
English spelling rule: Words almost never end in just ⟨v⟩ — there's nearly always a silent ⟨e⟩ after it (love, have, give, move). The few exceptions are recent borrowings like "rev" or abbreviations.
Unusual spellings (~1%)
⟨f⟩
Exactly one common word spells /v/ with ⟨f⟩.
Just one word: "Of" is the only common English word where ⟨f⟩ makes the /v/ sound. This is a historical quirk — the word was once pronounced with /f/ but shifted to /v/ while keeping its spelling.
⟨ph⟩
One name uses ⟨ph⟩ for /v/.
Stephen vs Steven: The name "Stephen" is pronounced exactly like "Steven" — the ⟨ph⟩ makes /v/, not /f/! This is the only common English word where ⟨ph⟩ = /v/.
