gusto (n.) Look up gusto at Dictionary.com
1620s, "very common from the beginning of the 19th c." [OED], from Italian gusto "taste," from Latin gustus "a tasting," related to gustare "to taste, take a little of," from PIE *gus-tu-, suffixed form of root *geus- "to taste; to choose." English first borrowed the French form, guste "organ of taste; sense of taste" (mid-15c.), but this became obsolete.
