Etymology

The word "expectation" originates from Latin exspectare ("to look out for"), combining ex- (out) and spectare (to look). The root pect (variant of spect) reflects the idea of "gazing" or "observing," metaphorically evolving into "anticipating." The suffix -ation nominalizes the action, turning it into a state of awaiting something. Over time, the spelling simplified from exspectation to expectation, but the core meaning of "looking forward to" remains intact.
