gust

The root gust comes from Latin gustāre, "to taste," and its noun gustus, "a taste" or "flavor." At its heart this root is about putting something in your mouth and judging it — and, by extension, about the appetite and relish that good food awakens. Tasting was never neutral for the Romans: a taste was either pleasing or it wasn't, and that built-in verdict is what gives the family its emotional charge.

The most famous member hides this origin completely. disgust = dis- (reversal, away) + gustāre (taste). Picture tasting something and your whole body recoiling — the reverse of a pleasant taste, a flavor so bad you want to spit it out. That literal "bad taste in the mouth" became a metaphor for any deep revulsion: you can now be disgusted by cruelty or corruption, things you never literally tasted. From it grow the everyday adjectives disgusting (the thing that causes the recoil) and disgusted (the person feeling it) — the classic -ing/-ed pair where -ing points outward at the cause and -ed points inward at the feeler.

At the opposite emotional pole sits gusto. English borrowed it from Italian gusto ("taste, liking"), itself straight from Latin gustus. If disgust is tasting something and pulling back, gusto is tasting something and diving in: doing a thing with gusto means doing it with the eager appetite of someone who loves their food. The flavor metaphor survived the trip through Italian intact — relish at the table became relish for life.

The plainest, most literal members are the academic ones: gustatory ("relating to the sense of taste") and gustation ("the act of tasting; the sense of taste"). These are the words scientists and food writers reach for — gustatory receptors, gustatory pleasure. They never drifted into metaphor; they simply kept Latin's literal meaning.

A few cousins live just outside English's core vocabulary but show the same root traveling through French: ragout (a richly seasoned stew, from French ragoûter, "to revive the taste") and degustation (a tasting menu, from déguster, "to taste carefully") — the word fancy restaurants use for a multi-course tasting. And reaching much further back, the Latin gustāre shares a Proto-Indo-European ancestor (ǵeus-, "to taste, to choose") with the Germanic verb choose — because to taste something is, in a sense, to test it and decide. That ancient link between tasting and choosing is the quiet logic under the whole family.

The one trap: the English noun gust ("a sudden rush of wind") looks identical but comes from Old Norse gustr, a Germanic word for a blast of air. Same spelling, entirely separate origin — a coincidence, not a relative.
