Etymology

It is from Latin praedictus, past participle of praedīcere (“to foretell, give notice”),[2][3][4] from prae-, before, and dīcere, to say (see diction),[2][3][5] perhaps as a back-formation from the earlier prediction (1561).[2][3]

Earliest recorded meaning

To mention earlier in a text: 1546, obsolete;[6] to foretell, 1590 in MWU, 1623 in the OED, the 1620s in Etymonline,[4][6][2] and 1671, in Milton's Paradise Regained, in Barnhart.[3]

Semantic evolution

The intransitive, to prophesy, is from 1652.[6] Of a theory, to have something as a deducible consequence, is from 1961.[6] In gunnery, to direct fire with a predictor is from 1943.[6] A noun predict, a prediction, was used about 1600.[6]
