From Middle English custume, borrowed from Anglo-Norman custume, from Old French coustume, from Vulgar Latin *cōnsuētūmen or *costūmen, from Latin cōnsuētūdinem, accusative singular of cōnsuētūdō (custom, habit), from cōnsuēscō (accustom, habituate), from con- (with) + suēscō (become used or accustomed to). First element con- derives from cum, from Old Latin com, from Proto-Italic *kom, from Proto-Indo-European *ḱóm (with, along). Second element suēscō is from Proto-Indo-European *swe-dʰh₁-sk-, from *swé (self) + *dʰeh₁- (to put, place, set); related to Latin suus (one's own, his own). Displaced native Middle English wune, wone (custom, habit, practice), from Old English wuna (custom, habit, practice, rite), Middle English side, sid (custom), from Old English sidu, sido (custom, note, manner), Middle English cure (custom, choice, preference), from Old English cyre (choice, choosing, free will). Doublet of costume and consuetude. Adjective form circa 1830.
