anticipate (v.)youdaoicibaDictYouDict
1530s, "to cause to happen sooner," a back-formation from anticipation, or else from Latin anticipatus, past participle of anticipare "take (care of) ahead of time," literally "taking into possession beforehand," from ante "before" (see ante) + capere "to take" (see capable).

Later "to be aware of (something) coming at a future time" (1640s). Used in the sense of "expect, look forward to" since 1749, but anticipate has an element of "prepare for, forestall" that should prevent its being used as a synonym for expect. Related: Anticipated; anticipating.
