Selected source glosses provide context, not a complete modern definition inventory

The adjective is derived from Middle English moist, moiste [and other forms], from Anglo-Norman moist, moiste, moste, Middle French moiste, and Old French moiste, muste (“damp, moist, wet”) (modern French moite); further etymology uncertain, perhaps a blend of a Late Latin variant of Latin mūcidus (“mouldy, musty”) + a Late Latin derivative of Latin mustum (“unfermented or partially fermented grape juice or wine, must”). The noun is derived from the adjective.

Source etymology 2

Original entry ↗
verb

To make (something) moist or wet; to moisten. · To inspire, to refresh (someone); also, to soften (one's heart). · To rain lightly; to drizzle. · To have an effect of moistening or wetting.

Selected source glosses provide context, not a complete modern definition inventory

From Middle English moisten, moist, moiste (“to make moist or wet; to soak in liquid; to become moist or wet; to provide with moisture or water; to satisfy thirst with liquor or water, slake”) [and other forms], and then either: * from Anglo-Norman muster (“to make moist or wet”), Middle French moistir, and Old French moistir (“to make moist or wet; to become moist or wet”) (compare enmoistir; modern French moitir), from Old French moiste, muste (“damp, moist, wet”) (see etymology 1) + -ir (suffix forming infinitives of second conjugation verbs); or * from Middle English moist, moiste (adjective) (see etymology 1), though the adjective is first attested later.
