Forms

équanimité f (plural équanimités)[1]

Etymology

It is borrowed from Latin aequanimitās (“good will, evenness of mind”), borrowed in 1572 by Amyot.[2][3][4] The Latin noun is formed from aequus (“equal, level”) and animus (“mind, spirit”) (or anima (“soul”)).[3][5][6] Littré derives it through the adjective aequanimus (“even-tempered”), which French also borrowed as équanime.[7][3]

It is related to égal, équitable and âme.[3]

Earliest recorded meaning

Amyot uses it in 1572, in De la tranquillité de l'âme et repos de l'esprit, for the calm, even temper of the soul: Cela donc est une de ces choses qui trouble l'equanimité et tranquillité d'esprit (“this, then, is one of the things that disturb the evenness and tranquillity of the mind”).[2][7]

Semantic evolution

The word kept the Latin sense of evenness of soul, but it was hardly used in the classical period of the 17th and 18th centuries.[3][5] It was taken up again in the 19th century: Boiste's dictionary records it in 1819 in the sense “impartiality”.[3][5] Littré still called it little used,[7] and it has stayed a literary word, used by writers such as Mérimée and Gide for a calm, steady temper.[3][2]

English equanimity is recorded about 1600, first meaning “fairness, impartiality”, from the French word.[8]
