actual:  In common with act, action, etc, actual comes ultimately from Latin āctus, the past participle of the verb agere ‘do, perform’. In late Latin an adjective āctuālis was formed from the noun āctus, and this passed into Old French as actuel. English borrowed it in this form, and it was not until the 15th century that the spelling actual, based on the original Latin model, became general. At first its meaning was simply, and literally, ‘relating to acts, active’; the current sense, ‘genuine’, developed in the mid 16th century. => act, action
early 14c., "pertaining to an action," from Old French actuel "now existing, up to date" (13c.), from Late Latin actualis "active, pertaining to action," adjectival form of Latin actus (see act (n.)). The broader sense of "real, existing" (as opposed to potential, ideal, etc.) is from late 14c.
