ExtractIn Roman law, the word actio refers to a civil lawsuit. At first sight, it seems obvious that actio derives from the verb ago, which has the basic meaning “to drive,” “to urge,” or simply “to act.” The Roman jurists themselves clearly regarded ago as the verb corresponding to the noun actio and meaning “to conduct a lawsuit” (cf. Festus, Gloss. Lat. 21, l. 15, s.v. agere). Hence, actio may be explained as referring to the claimant urging the judge (and/or the adversary) to do something,1 or simply to the claimant’s actions in court.2 Some scholars have proposed different etymologies. It seems possible that actio is not a derivative of ago (“to drive, to urge”), but of a root agjō meaning “to speak” (cf. the verb aio), and that the word was only later associated with ago.3 Alternatively, it has been argued that ago and aio have a common root that, in the context of archaic law, refers to a performative utterance which affects the Roman citizens collectively.
