bolero

the word 'bolero' entered english directly from spanish in the late 18th century, referring to the traditional spanish dance. the spanish term likely derives from 'volero', meaning 'flying', from 'volar' (to fly), perhaps alluding to the light, quick movements of the dance. the name for the short jacket, which emerged in the mid-20th century, was borrowed from the dance's name, possibly inspired by the costume worn by dancers or simply by association with spanish style. thus, the term traveled from describing a dynamic, rhythmic art form to denoting a specific article of fashion.

this word is a loanword from spanish. it is not productively formed from smaller, meaningful english morphemes and is therefore treated as unsegmentable in the context of english word formation.
