Forms

monstre m (plural monstres)[1] Old French mostre (1160) beside monstre.[2][3]

Etymology

It is borrowed from Latin mōnstrum (“portent, prodigy; monster”).[3][4][5][1] The Latin word comes from moneō (“to remind, warn”): in religious language it was a prodigy warning of the will of the gods, then any exceptional object or supernatural being, and in Christian Latin especially a demon.[3][4][2] Comedy used it of people, as in Terence's “monstrum hominis” and Plautus's “monstrum mulieris”.[3][4] montrer belongs to the same family, but its Latin source mōnstrō had already lost the religious sense and meant only “to show”.[6][7]

It matches Old Occitan mostre, Spanish monstruo, Portuguese monstro and Italian mostro.[7]

Earliest recorded meaning

The Oxford Psalter (first half of the 12th century) has it for a divine prodigy or miracle, translating Latin signa and prodigia: les ovres del seigneur, les queles il posat monstres sur terre.[3][4]

Semantic evolution

The Roman d'Eneas (1160) uses mostre of Cacus, a fabulous being of legend, and, from the 12th century it was said of people: a man of strange looks and ways (1165), a leper (1223), a deformed man (1225), and, from the 17th century a very ugly person (1690).[3][4] Monstre marin dates from 1561–1562, and in the 17th century it was said of the large fish served at table (1678).[4][8]

The general sense declined: “a monstrous, criminal act” (1541, Calvin), “an incredible thing” (1580, Montaigne) and “a badly ordered thing”, a building without symmetry or a learned book without order (1690, Furetière).[3][4] As a moral judgement it named a cruel or depraved person;[3][4] un monstre de cruauté is in Furetière (1690), and by antiphrasis Mme de Genlis could say c'est un monstre! of an adorable pouffe (1779).[3][4] The adjective monstre “huge, colossal”, as in un effet monstre, is from 1841;[3][1] monstre sacré, a great star, is a modern phrase.[3][1]
