Etymology
the word 'actuate' originates from the medieval latin actuatus, the past participle of actuare, meaning "to put into motion." this verb itself is derived from the latin actus, signifying "a doing, a driving," which comes from the verb agere ("to drive, lead, do"). the core root ag- is traceable to the proto-indo-European h₂eǵ- ("to drive, draw, move"), a root associated with movement and action. thus, the literal construction "to make (ate) driven (act)" evolved logically into the modern abstract meanings of setting a mechanism in motion or motivating a person to action.
