Etymology

trio = tri<three> + o<noun suffix>

  • tri (from Latin tres, meaning "three")
  • o (a noun-forming suffix, often used in musical terms like "duo" or "quartet")

Etymology Origin:
The word "trio" originates from Italian, derived from the Latin tres (three). It entered English in the 18th century, primarily in musical contexts, to denote a group of three performers or a composition for three voices/instruments. The suffix "-o" is typical in Italian musical terminology, reflecting its Romance language roots. The logic is straightforward: "tri-" (three) + "-o" (noun suffix) = "a group of three."
