Origin

Middle English (in the general sense 'testing, or a test of, the merit of someone or something'): from Old French assai (noun), assaier (verb), variant of essai 'trial', essayer 'to try' (see essay).

essay from Late Middle English:
Essay is a variant of assay (Middle English) ‘try, test’, going back to Latin exigere ‘ascertain, weigh’. In writing contexts, it referred initially to ‘a first draft’ but came to mean ‘a composition’. This use seems to have been taken from the French philosopher and essayist Montaigne (1533–92) whose Essais were first published in 1580.
