1530s, "state or condition of waiting or awaiting with confident anticipation," from French expectation (14c.) or directly from Latin expectationem/exspectationem (nominative expectatio/exspectatio) "anticipation, an awaiting," noun of action from past-participle stem of expectare/exspectare "await, look out for" (see expect).
