Meticulous Has Fearful Roots

We're afraid we have some strange etymological news: meticulous comes from the Latin word for "fearful"—metīculōsus—and ultimately from the Latin noun metus, meaning "fear." Although meticulous currently has no "fearful" meanings, it was originally used as a synonym of "frightened" and "timid." This sense had fallen into disuse by 1700, and in the 1800s meticulous acquired a new meaning of "overly and timidly careful" (possibly due to the influence of the French word méticuleux). This meaning in turn led to the current one of "painstakingly careful," with no connotations of fear at all. The newest use was controversial for a time, but it is now by far the most common meaning; even the most meticulous (or persnickety, depending on your view) among us consider it perfectly acceptable.

Word History

Etymology

earlier, "fearful," borrowed from Latin metīculōsus, metūculōsus "timid, apprehensive," from metū-, stem of metus "fear, dread" (of uncertain origin) + -culōsus (in perīculōsus "involving danger, perilous")

Note: The senses "overscrupulous," then "careful, scrupulous" may depend on French méticuleux, for which these meanings are attested somewhat earlier than in English.
