The OLD's earliest citations are from Plautus, of something threefold.[2] Köbler dates Plautus c. 250–184 BC.[3]

It meant threefold, occurring three times, and with plural nouns three together, as in Plautus.[2] In Horace the neuter meant three times as much, in Caesar it meant made of three equal parts, as a triple line of battle, and in Varro made of three different parts.[2]

In Ecclesiastical Latin it meant triple, threefold.[4] Medieval Latin used it as triplus “threefold”.[5] British Medieval Latin used it of sets of three and in music of three-part writing.[6] It was borrowed into Italian triplice and English triplex.[1]
