"a taste, flavor, savor" especially a slight flavor that suggests something, from Old English smæc "taste; scent, odor," from Proto-Germanic *smakka- (source also of Old Frisian smek, Middle Dutch smæck, Dutch smaak, Old High German smac, German Geschmack, Swedish smak, Danish smag), from verb *smakjanan, from a Germanic and Baltic root meaning "to taste" (source also of Lithuanian smaguriai "dainties," smagus "pleasing"). Meaning "a trace (of something)" is attested from 1530s.
plant of the mint family, late 14c., from Old French thym, tym (13c.) and directly from Latin thymum, from Greek thymon, which had been derived from PIE root *dheu- (1), base of words meaning "smoke," for its scent or from being burned as a sacrifice, but Beekes finds this "doubtful" and suggests that "As a local plant name, the word is liable to be of Pre-Greek origin." Related: Thymic.
1530s, "cat-like quadruped of northern Africa," from French civette (15c.), ultimately (with Italian zibetto, Medieval Latin zibethum, Medieval Greek zapetion) via lost intermediate forms from Arabic zabad "civet," which is said to be related to zabad "foam, froth," zubd "cream," but perhaps this is folk-etymology of an African name. As "secretion of the anal glands of a civet-cat," one popular in perfumes, from 1550s. Hence, as a verb, "to scent with perfume" (c. 1600). Related: Civited.
metallic element of the platinum group, 1803, coined in Modern Latin by its discoverer, English chemist Smithson Tennant (1761-1815) from Greek osmē "smell, scent, odor" good or bad, from PIE root *hed- "to smell" (see odor). With metallic element ending -ium. So called for the pungent smell of its oxide, a highly poisonous acid. The densest stable element, it commonly is found in alloy with iridium.
