About This Root
The root quest comes from Latin quaerere, 'to seek, to ask,' and its noun quaestiō, 'a seeking, an inquiry.' Picture a Roman official sent out to seek the facts of a case — that act of searching for an answer is the seed of the whole family.
The most direct descendant is question itself: literally 'a thing sought.' When you ask a question, you are seeking information. Add the prefix in- (into) and you get inquire — to seek INTO a matter — and its noun inquiry, the formal seeking-into we call an investigation. The adjective inquisitive describes someone whose nature is to keep seeking, keep asking — curious, sometimes nosily so.
From 'asking' it is a short step to 'doubting.' To question a claim is to ask whether it holds up; questionable means 'open to being asked about,' i.e. doubtful, dodgy. Pile on the negatives and you reach unquestionable (cannot be doubted) and unquestioning (accepting without asking) — two words that point in opposite directions from the same idea of asking.
Two members wander further from 'seek' and reward a second look. exquisite is ex- (out) + the quaerere stem: originally 'carefully sought out,' something searched for so thoroughly that it is choice, refined, beautiful. perquisite (the formal word behind the casual 'perk') is per- (thoroughly) + quaerere: something thoroughly sought after and obtained — an extra benefit beyond your basic pay.
The spelling shifts between quest-, quir-, quis-, and quisit- (question, inquire, inquisitive, exquisite), but the throughline never changes: every one of these words is about seeking — for information, for truth, for something fine, for an answer.
A quest is a search — and every quest- word is about seeking. A question seeks an answer; to inquire is to seek into something; an inquisitive child keeps seeking; exquisite means 'sought out so carefully it's perfect.'
Core Words Deep Dive
The few words from this family worth telling in full — one by one.
The literal anchor of the family — 'a thing sought.' The leap worth noticing is from asking to doubting: 'I have a question' (seeking info) versus 'I question that claim' (expressing doubt). Both are the same act of seeking, aimed once at information and once at truth.
The family's most surprising member. ex- (out) + quaerere (seek) = 'carefully sought out.' Something searched for so thoroughly that it became choice and refined — hence today's 'extremely beautiful, finely made.' Note the stress can fall on either syllable: EX-quisite or ex-QUIS-ite.
in- (into) + the quis- form of quaerere + -itive = 'inclined to seek into things.' It carries a faint double edge: praiseworthy curiosity ('an inquisitive mind') but also nosiness ('inquisitive neighbors'). Context tells you which.
per- (thoroughly) + quaerere (seek) = 'something thoroughly sought after and obtained.' Originally a privilege claimed beyond one's wage; the clipped, casual form perk is far more common today, but perquisite survives in formal and legal writing.
Related Roots
Both involve searching, but quest is asking/seeking for an answer (question, inquire), while scrut is examining closely (scrutinize, scrutiny). Asking out loud → quest; peering carefully → scrut.
rog also means 'ask' (interrogate, ask formally). quest leans toward seeking information or things (question, perquisite); rog leans toward demanding/requesting an answer (interrogate, ask for a vote).
