Etymology

The word "act" originates from the Latin actus (a doing, driving, or performance), derived from the verb agere (to do, drive, or lead). This root is also present in words like "action," "agent," and "active." Over time, "act" evolved in English to broadly signify any deed, performance, or division of a dramatic work, retaining its core sense of movement or execution.
