English

Etymology

From Middle English necessarye, from Old French necessaire, from Latin necess?rius (“unavoidable, inevitable, required”), variant of necesse (“unavoidable, inevitable”), probably from ne or non cessum, from the perfect passive participle of c?d? (“yield; avoid, withdraw”); see cede.

Older use as a noun in reference to an outhouse or lavatory under the influence of English and Latin necess?rium, a medieval term for the place for monks' "unavoidable" business, usually located behind or attached to monastic dormitories.
