Earliest recorded meaning

The OLD's earliest citations are from Plautus, of words spoken and of a saying.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant what is said, an utterance, one's words, and a saying, witty remark, maxim, as in Plautus.[2] Etymonline adds the senses of a prophecy and an order.[3]

In Ecclesiastical Latin it meant a word, saying, command.[5] Medieval Latin used it for an arbitral award.[6] It survives in Italian detto, French dit and Spanish dicho, and was borrowed into English as dicte “a saying” in the late 14th century and as English dictum in the 1660s.[1][3]
