Morphology

surveillance = surveil (semi-transparent) = surveil + ance

Built from the verb 'surveil' plus '-ance'; the meaning is predictable from the verb, but the verb and its parts are borrowed from French and are not fully productive or transparent to many learners.

Etymology

The word surveillance comes from French parts sur- ('over') and veiller ('to watch'), so it literally means 'watching over' someone or something. That's why surveillance today means careful, ongoing watching, often by police or cameras.
