Examples

Etymology

Via an East Anglian dialect, from some Scandinavian (North Germanic) language, related to Danish terne, Norwegian terne, and Swedish tärna, all from Old Norse þerna (“tern; maidservant”), ultimately from Proto-West Germanic *þewernā (“handmaid, young girl”). First attested in the 1670s.

PIE word *tréyes The noun is derived from Late Middle English terne (“throw of a die or dice showing the number three”), from Old French terne (“gathering of three people; trinity”) (modern French terne), from Latin ternās, the accusative feminine plural of ternī (“three each; three at a time”), from ter (“thrice”) (ultimately from Proto-Indo-European *tréyes (“three”)) + -ī (from -us (suffix forming adjectives)). The adjective is either derived from the noun, or directly from Latin ternī (“three each; three at a time”); see above.
