Past tense of inquire; to ask questions in order to find out information or investigate something.
From Old French 'enquerre,' from Latin 'inquirere' (to seek into), combining 'in-' (into) + 'quaerere' (to seek); entered Middle English around the 1200s.
English has both 'inquire' and 'enquire' (the British spelling), but they've been drifting apart—'inquire' now tends toward investigative questioning while 'enquire' sounds more polite and general, showing how even spelling variations can develop semantic differences.
