[Middle English, from Old French acte, from Latin āctus, a doing, and āctum, a thing done, both from past participle of agere, to drive, do; see ag- in Indo-European roots.]
ac'ta·bil'i·ty n., act'a·ble adj.
Usage Note: The words act and action both mean "a deed" and "the process of doing." However, other senses of act, such as "a decision made by a legislative body" and of action, such as "habitual or vigorous activity" show that act tends to refer to a deed while action tends to refer to the process of doing. Thus, people engage in sex acts but not sex actions. By the same token, a person may want a piece of the action, but not a piece of the act. The demands of meaning or idiom will often require one word or the other. But in some cases either can be used: my act (or action) was premature.

Word Origin & History

act  (n.)
c.1384, from O.Fr. acte, from L. actus "a doing" and actum "a thing done," both from agere "to do, set in motion, drive, urge, chase, stir up," from PIE root *ag- "to drive, draw out or forth, move" (cf. Gk. agein "to lead, guide, drive, carry off," agon "assembly, contest in the games," agogos "leader;" Skt. ajati "drives," ajirah "moving, active;" O.N. aka "to drive;" M.Ir. ag "battle"). Theatrical (1520) and legislative (1458) senses of the word also were in Latin. The verb is first attested 1475; in the theatrical performance sense it is from 1594. In the act "in the process" is from 1596, originally from the 16c. sense of the act as "sexual intercourse." Act of God "uncontrollable natural force" first recorded 1882. To act out "behave anti-socially" (1974) is from psychiatric sense of "expressing one's unconscious impulses or desires."
