gusto

The word 'gusto' entered English in the early 17th century directly from Italian, where it means 'taste'. The Italian term itself derives from Latin 'gustus', with the same meaning. This Latin root is traced back to the Proto-Indo-European root ǵews-, meaning 'to taste' or 'to choose'. The semantic journey from the literal sense of 'taste' to the figurative meaning of 'keen relish or enthusiasm' is a classic example of metaphorical extension, where a physical sensation is used to describe an energetic mental or emotional engagement. The modern abstract meaning captures the idea of doing something with the same kind of keen enjoyment one might have when savoring a delicious flavor.

Structure: gust (taste) + o (noun suffix) 'gust' is from Latin 'gustus', meaning 'taste'. The suffix '-o' is a common noun-forming suffix in English, often borrowed from Italian or Spanish.
