Etymology

The word "require" originates from Latin requirere ("to seek again, demand"), combining re- (expressing repetition) and quaerere ("to seek"). Over time, it evolved in Old French as requerre before entering Middle English as "require," retaining its core meaning of demanding or needing something. The suffix -ed marks it as a past participle (e.g., "required courses") or past tense verb (e.g., "He required proof"). The morpheme quire is preserved in related words like "inquire" (to seek information).
