disgust: [16] Something that disgusts one is literally ‘not to one’s taste’. The word comes from Old French desguster, a compound verb formed from the prefix des- ‘not’ and goust ‘taste’. This in turn came from Latin gustus (ultimate source of English gusto); its modern French descendant is goût. Originally, as its derivation implies, disgust meant simply ‘cause to feel aversion, displease’ (and also, with subject and object reversed, ‘dislike, loathe’: ‘Had he not known that I disgusted it, it had never been spoke or done by him’, Robert South, Sermons 1716); but over the centuries it has hardened into ‘sicken, repel’. => gusto
disgust (n.)
1590s, from Middle French desgoust "strong dislike, repugnance," literally "distaste" (16c., Modern French dégoût), from desgouster "have a distaste for," from des- "opposite of" (see dis-) + gouster "taste," from Latin gustare "to taste" (see gusto).
disgust (v.)
c. 1600, from Middle French desgouster "have a distaste for" (see disgust (n.)). Sense has strengthened over time, and subject and object have been reversed; the older use looks like this: "It is not very palatable, which makes some disgust it" (1660s). The reverse sense of "to excite nausea" is attested from 1640s. Related: Disgusted; disgusting.
