How does Aristophanes criticize Euripides in The Frogs?

In his literary comedy Frogs (405 BCE), Aristophanes presents a critical assessment of Euripides by staging a dramatic competition between him and his predecessor, Aeschylus.

Aristophanes uses this contest to highlight perceived flaws in Euripides' work, which he often parodied for its "chatter" (lalia), light weight, and volubility. While Euripides was known for his psychological realism and focus on human flaws, Aristophanes contrasts this with the more austere and lofty tradition of Aeschylus. Through the character of Dionysus, the god of drama, the play ultimately concludes that Aeschylus is the superior poet to help Athens navigate its contemporary troubles.1234

Beyond his stylistic critiques, Aristophanes frequently mocked Euripides' personal background, including jokes about his mother being a greengrocer. By choosing to return to the land of the living with Aeschylus rather than Euripides, Dionysus serves as the vehicle for Aristophanes' judgment that Euripidean tragedy lacked the moral weight and civic utility required by the state during the Peloponnesian War.534
