1530s, "fearful, timid," a sense now obsolete, from Latin meticulosus, metuculosus "fearful, timid," literally "full of fear," from metus "fear, dread, apprehension, anxiety," a word of unknown origin. The old word seems to have become archaic after c. 1700, fossilized in a passage of Sir Thomas Browne, though it turns up occasionally and obscurely as late as 1807.
It began to return to English in a sense of "fussy about details" by 1840s, from French méticuleux "timorously fussy" [Fowler, who rails against it, attributes this use in English to "literary critics"], the French descendant of the Latin word, but it took time for this to percolate. Meticulous appears 1852 in Halliwell's "Dictionary of Archaic and Provincial Words" (with the definition "timorous") and is marked "obsolete" in Craig's dictionary of the same year. It was listed by Richard Trench ["English Past and Present," 1868], who started the movement that became the OED, among the words that had been "rejected and disallowed by the true linguistic instincts of the national mind."
It is marked archaic in the Imperial Dictionary (1883), which has only the sense "timid," but not so marked in Century Dictionary (1890), which defines it as "Timid; over-careful." It was much criticized, and somewhat defended, in writerly publications c. 1914-1924. Related: Meticulosity.
by 1996, from metropolitan + -sexual, ending abstracted from homosexual, heterosexual. Wikipedia defines it as "a portmanteau of metropolitan and heterosexual, coined in 1994 describing a man who is especially meticulous about his grooming and appearance, typically spending a significant amount of time and money on shopping as part of this."
Nevertheless, the metrosexual man contradicts the basic premise of traditional heterosexuality—that only women are looked at and only men do the looking. Metrosexual man might prefer women, he might prefer men, but when all's said and done nothing comes between him and his reflection. [Mark Simpson, "It's a Queer World," 1996]
"a vigil beside a dying person," 1865, from death + watch (n.) "a watching." The death-watch beetle (1660s) inhabits houses, makes a ticking noise like a pocket-watch, and was superstitiously supposed to portend death.
FEW ears have escaped the noise of the death-watch, that is, the little clicking sound heard often in many rooms, somewhat resembling that of a watch; and this is conceived to be of an evil omen or prediction of some person's death: wherein notwithstanding there is nothing of rational presage or just cause of terror unto melancholy and meticulous heads. For this noise is made by a little sheathwinged grey insect, found often in wainscot benches and wood-work in the summer. [Browne, "Vulgar Errors"]
