actual

The word 'actual' has a journey from the concrete to the abstract. It originates from the Latin verb agere, meaning "to do, drive, or set in motion." Its past participle, actus, gave rise to the noun actus (an act, a performance). The Late Latin adjective actualis was formed from this noun, meaning "pertaining to action or performance." In medieval philosophy, actualis was used to denote something existing in reality (in act), as opposed to merely in potential. This philosophical distinction was inherited into Middle English via Old French, where 'actual' came to mean "real, existing in fact," shifting from the realm of action to the realm of existence.
