v.

1530s, “to cause to happen sooner,” a back-formation from antic-p-tion, or else from latin antic-p-tus, past participle of antic-p-re “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 antic-p-te has an element of “prepare for, forestall” that should prevent its being used as a synonym for expect. related: antic-p-ted; antic-p-ting.
