Origin

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.
