Etymology: "Sestettos" is simply the plural of "sestetto," an Italian word for a group of six performers. The Italian term is built on "sei," meaning six, which descends from Latin "sex," and the "-etto" ending is a diminutive-style suffix that Italian uses for many musical and small-scale terms. The same pattern appears in "duetto" (two), "terzetto" (three) and "quartetto" (four), so a sestetto belongs to a clear numerical family of ensemble names. The plural form matters because English has absorbed the Italian term along with the musical tradition it describes. Italian plurals of nouns ending in "-etto" change the final vowel to "-i" (sestetti), but English speakers often keep the "-os" ending, giving "sestettos." Both forms appear in English usage, and the Italian-style plural is the one a musician or dictionary would normally expect.
