Forms

cōnsuētus (feminine cōnsuēta, neuter cōnsuētum, superlative cōnsuētissimus); first/second-declension adjective[1][2]

Etymology

It is the perfect passive participle from Latin cōnsuēscō (“to become accustomed”), used as an adjective.[1][3][4] De Vaan lists ⟨cōnsuēscere⟩ among the compounds of suēscō (“to become accustomed”), an inchoative from Proto-Italic *swē(þ)-sk-e/o- and Proto-Indo-European *sue(h1-)dhh1- (“to make one's own, get accustomed”); he notes that the compounds are older than the simple verb, which is a back-formation.[5] Cognate with Ancient Greek ἦθος (êthos, “custom, usage”).[5]

Earliest recorded meaning

It is found first in Plautus' Vidularia, in talis iactandis tuae sunt consuetae manus, “your hands are used to throwing dice”.[6][4]

Semantic evolution

It means accustomed or used to something, as of animals used to one another in Varro,[1][4] and, of things, customary, habitual or usual:[1][2] Terence's Andria has a familiar love that was easy to see, Sallust a usual lust and familiar dangers, and Virgil consueta antra, the usual caves.[1][2][4] Ovid uses it of ordinary words, and the superlative consuetissima verba, “the most familiar words”.[1][2]

In Ecclesiastical Latin it means accustomed, usual or customary,[7] as in the Vulgate's usual number of bricks.[2] It continues in Italian consueto.[4]
