noctuary (n.) — non-fiction (adj.)

noctuary (n.)

"account of what passes in the night," the converse of a diary, 1714; as though from Latin *noctuarius; see noct- "night." A word in use 18c.-19c.

nocturn (n.)

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).

nocturnal (adj.)

"of or pertaining to the night, used or done at night," late 15c. (Caxton), from Old French nocturnal "nightly, nocturnal," or directly from Late Latin nocturnalis, from Latin nocturnus "belonging to the night," from nox (genitive noctis) "night," cognate with Old English neaht (see night) + -urnus, suffix forming adjectives of time. Related: Nocturnally. Nocturnal emission "involuntary ejaculation during sleep" is recorded by 1813.

nocturne (n.)

1851, "musical composition of a dreamy character," properly instrumental, from French nocturne, literally "composition appropriate to the evening or night," noun use of Old French nocturne "nocturnal," from Latin nocturnus (see nocturnal). The style and the name are said to have originated c. 1814 with Irish-born composer John Field, who wrote many of them, in a style that Chopin mastered in his own works, which popularized the term. But Field's work seems to have been appreciated in German and French publications before it came to attention in England in 1851.

nocuous (adj.)

1630s, "noxious, harmful," from Latin nocuus "harmful," from stem of nocere "to hurt, injure, harm" (from PIE root *nek- (1) "death"). Especially of venomous serpents.

nod (v.)

late 14c., "to quickly bow the head; to assent, beckon, or salute quickly by an inclination of the head," late 14c., nodden, a word of unknown origin, probably an Old English word, but not recorded, or perhaps from a Low German word related to Old High German hnoton "to shake," from Proto-Germanic *hnudan (OED considers this "doubtful"). Apparently unrelated to Latin nuere "to nod." Related: Nodded; nodding.

Meaning "droop the head forward with a short, involuntary motion," as when drowsy, is by 1560s. Figurative sense of "be guilty of a lapse, be momentarily inattentive" is by 1670s, echoing Horace's dormitat Homerus. Of flowers, etc., "to droop or bend downward," c. 1600. Meaning "to drift in and out of consciousness while on drugs" is attested by 1968 (as a noun in this sense by 1942).

A nodding acquaintance (by 1821) is one you know just well enough to recognize with a nod. Land of Nod "state of sleep" (1731) is a pun on the biblical place name east of Eden (Genesis iv.16).

The modern word in English, with the sense "a Christmas carol" (1811) probably is a separate borrowing from French. As a masc. proper name, it is from Old French, probably literally "of or born on Christmas."

noematic (adj.)

"of or pertaining to the understanding, mental, intellectual," 1860, with -ic + Greek noēma "a perception, a thought," from noein "to see, perceive, have mental perception," from noos "mind, thought," which is of uncertain origin. Related: Noematical (1680s); noematically.

nog (n.)

1670s, boull of nogg, as something shared with company; a poem of the same decade describes sweet nog. Attested by 1690s as "old, strong type of beer brewed in Norfolk." The word is of unknown origin; perhaps related to noggin. Also see egg-nog. Related: Noggy "tipsy, intoxicated."

noggin (n.)

1620s, "small cup, mug," later of the contents of such a vessel, "small drink" (1690s), a word of unknown origin, possibly related to Norfolk dialectal nog "strong ale." OED considers that the similar Celtic words are "no doubt" from English. Informal meaning "head" is attested by 1866 in American English.

no-go (adj.)

"where it is forbidden to go," 1971, from no + go (v.). Earlier it was a noun phrase for an impracticable situation (1870) and a type of horse race (by 1860).

noise (n.)

c. 1200, "sound of a musical instrument;" mid-13c., "loud speech, outcry, clamor, shouting;" c. 1300, "a sound of any kind from any source," especially a loud and disagreeable sound, from Old French noise "din, disturbance, uproar, brawl" (11c., in modern French only in phrase chercher noise "to pick a quarrel"), also "rumor, report, news," a word of uncertain origin, replacing Replaced native gedyn (see din).

According to some, it is from Latin nausea "disgust, annoyance, discomfort," literally "seasickness" (see nausea). According to others, it is from Latin noxia "hurting, injury, damage." OED considers that "the sense of the word is against both suggestions," but nausea could have developed a sense in Vulgar Latin of "unpleasant situation, noise, quarrel" (compare Old Provençal nauza "noise, quarrel"). Confusion with annoy, noisome, and other similar words seems to have occurred.

From c. 1300 as "a disturbance; report, rumor, scandal." In Middle English sometimes also "a pleasant sound." In 16c.-17c. "a band or company of musicians." Noises off, as a stage instruction in theater, "sound effects, usually loud and confused, made off stage but to be heard by the audience as part of the play," is by 1908.
