This entry reminds us, as it no doubt reminded its first readers, that the word drama properly meant a '(decisive) act', deriving as a "concrete" verbal noun in -ma from the verb dra/w 'act, achieve' (delta 1488, delta 1489). The semantic history of the word to mean a play acted in a theatre is unclear. The ancient word for an actor, u(pokri/ths, means an 'answerer', referring to his role in the earliest tragedies in answering the choral songs of a chorus. In this entry I translate the related noun as 'playing a speaking part', but by the time of the Suda it meant no more than dramatic performing. It also meant the 'declaiming' of an orator, and this meaning might suit the citation better than "in imitation as in acting a part."
Some scholars link the word to the use of the verb dra/w for performing a sacrifice (LSJ II, web address 1; cf. delta 1508, delta 1510), a ritual that almost certainly lay at the origin of the first dramas.
