gusto: [17] Gusto originally meant ‘taste’. It was borrowed from Italian gusto, which, like French goût, comes from Latin gustus ‘taste’. Its semantic progress from ‘taste’ via ‘liking for a particular food’ and ‘liking in general’ to ‘zest, enthusiasm’ is paralleled in relish. (Latin gustus itself came from an Indo-European *geus-, which also produced English choose.) => choose[gusto etymology, gusto origin, 英语词源]
