Count: 0 — No Russian words begin with the Latin letter Q. When you search for “Russian words that start with Q,” authoritative sources such as the Russian National Corpus, major dictionaries, and Wiktionary return no Cyrillic headwords that map to a Latin initial Q. Note an interesting detail: Russian uses the Cyrillic alphabet and common transliteration systems (BGN/PCGN, ISO) map any foreign /q/ sounds to К or КВ in Russian, so the Latin letter Q simply does not appear at the start of native Russian entries.

Understand why the specific criteria yields no results. The Cyrillic alphabet used for Russian contains no letter that corresponds to the Latin Q, and Russian phonology lacks the uvular stop /q/ that Q represents in languages like Arabic. Accept that foreign names and loanwords with a written Q in their original Latin form are adapted into Russian with К, Г, or combinations like КВ, so the Russian headword starts with Cyrillic К (or another letter) rather than a Cyrillic equivalent of Q. Consult respected references and you will see consistent adaptation rules rather than any native Q-initial entries.

Check related categories instead of insisting on Q-initial Russian words. Look for foreign names (Qatar, Quesada) and loanwords where the original language uses Q; find their Russian spellings under Катар, Кесада, etc. Consider languages written in Cyrillic that do include a letter for /q/ (for example Kazakh Қ) but not standard Russian. Use transliteration tables and bilingual dictionaries when you need matches for Latin Q, and consult the Russian National Corpus or major dictionaries for verified spellings and example sentences.
