predict v.

"act of predicting; a prophecy, a declaration concerning future events," 1560s, from French prédiction and directly from Medieval Latin predictionem (nominative predictio), from Latin praedictio "a foretelling," noun of action from past-participle stem of praedicere "assert, proclaim, declare publicly" (see predict).

Prediction may or may not be an inspired act : it is most commonly used of the foretelling of events in accordance with knowledge gained through scientific investigations or practical experience .... [Century Dictionary]

word-forming element meaning "before," from Old French pre- and Medieval Latin pre-, both from Latin prae (adverb and preposition) "before in time or place," from PIE *peri- (source also of Oscan prai, Umbrian pre, Sanskrit pare "thereupon," Greek parai "at," Gaulish are- "at, before," Lithuanian prie "at," Old Church Slavonic pri "at," Gothic faura, Old English fore "before"), extended form of root *per- (1) "forward," hence "beyond, in front of, before."

The Latin word was active in forming verbs. Also see prae-. Sometimes in Middle English muddled with words in pro- or per-.
