chile

The word "chile" for the pepper has a distinct journey from the Nahuatl word "chīlli," which referred to the hot pepper plant. Spanish explorers adopted this term during their contact with Aztec civilization in Mexico, and it entered English via American Spanish. The country name "Chile" is believed to have a separate, possibly indigenous South American origin, with theories linking it to a native word meaning "where the land ends" or "cold." The identical spelling for the pepper and the country in English is a coincidence of phonetic adaptation, representing two different borrowings into the language.

This is a loanword from Spanish, which itself borrowed it from the indigenous Nahuatl language (via Mexican Spanish). The word's origin is not further segmentable into meaningful morphemes within English.
