Etymology: The English "couplet" is a straightforward borrowing: it came from French "couplet," a diminutive of "couple" with the suffix "-et," so the word literally means "a little pair." The French term carried the same basic idea of two things joined together, and English took it up for a pair of lines that belong together in verse. The surprise lies in its family tree. "Couplet" is a doublet of "cabaletta," the name of a short, simple song form in Italian opera. Two words that started from the same root ended up in very different corners of the arts, one describing a pair of rhymed lines and the other a brief operatic aria, showing how a single idea of "pairing" branched across languages and genres.
