canonical hour, mid-13c., from Old French matines (12c.), from Late Latin matutinas (nominative matutinæ) "morning prayers," originally matutinas vigilias "morning watches," from Latin matutinus "of or in the morning," associated with Matuta, Roman dawn goddess (see manana). Properly a midnight office (occupied by two services, nocturns and lauds) but sometimes celebrated at sunrise. The Old English word was uht-sang, from uhte "daybreak."
from Spanish mañana, "tomorrow," from cras manñana, literally "tomorrow early," from Vulgar Latin *maneana "early," from Latin mane "in the morning," from PIE *ma- "good," with notion of "occurring at a good time, timely, early" (compare matins; and see mature (v.)). "Often taken as a synonym of easy-going procrastination said to be found in Spanish-speaking countries" [OED].
"afternoon performance, an entertainment held in the daytime," 1848, from French matinée (musicale), from matinée "morning" (with a sense here of "daytime"), from matin "morning" (but here "afternoon" or "daytime"), from Old French matines (see matins). Originally as a French word in English; it lost its foreignness by late 19c. For the French suffix, compare journey.
also nocturne, name of a division of the office of matins said just before daybreak (in the early Church a service recited after midnight), c. 1200, from Old French nocturne "evening service; curfew," from Medieval Latin nocturna, "group of Psalms used in the nocturns," from Latin nocturnus "pertaining or belonging to the night" (see nocturnal).
c. 1200, dirige (the contracted form is from c. 1400), "that part of the Office for the Dead beginning with the antiphon for the first psalm of the first nocturn of matins," from Latin dirige "direct!" imperative of dirigere "to direct" (see direct (v.)). The antiphon begins, Dirige, Domine, Deus meus, in conspectu tuo viam meam ("Direct, O Lord, my God, my way in thy sight"), from Psalms v.9.
Hence, broadly, "the funeral service as sung." Transferred sense of "any funeral song or hymn, a song or tune expressing grief" is from c. 1500.
Extended sense of "nonhistorical or mythical story," with or without saints, wonders, and miracles is first recorded late 14c. Meaning "writing or inscription" (especially on a coin or medal) is from 1610s; on a map, illustration, etc., from 1903. To be a legend in (one's) own time is from 1958.
