The Clouds both is and is not a typical Aristophanic comedy. The Clouds can be considered a typical Aristophanic comedy for formal and thematic reasons. First, the play follows many of the traditional formal divisions within a drama. Traditional formal divisions include an introductory "prologue" which provides the necessary exposition and background; the "parados," or song sung, by the chorus as the make their entrance; the "parabasis," a highly regulated diversion from the main plot, as sung in alternating songs and speeches by the chorus; the "agon," or formalized debate between two characters over a theme or issue central to the action of the play; sometimes a second "parabasis" or diversion; and finally, an "exodus," or song of conclusion sung by the chorus at the end of the ultimate celebration on which the play closes. Other less formal but no less typical elements include the scene wherein one character seeks help from another character and goes to petition them by knocking on their neighboring door. The Clouds fulfills all these formal conventions and tropes except for the final "exodus" or celebration song.
Not only does The Clouds meet the formal expectations of an Aristophanic comedy, but it revisits some of the thematic concerns. Earlier plays, such as The Acharnians and the no-longer-extant The Banqueters, employed the tensions between old and young men as well as city folk and country folk to produce vivacious comedies with moral messages. The Clouds, with its discussion of city versus country values and its quest for the proper education for young men, gives Aristophanes a chance to reemphasize existing themes in hopes of educating and better advising his fellow Athenian citizens.
However, The Clouds is an intriguingly unfinished tragi-comedy whose violent ending comes as a sharp departure from the concluding revelry of earlier plays. The fact that The Clouds lacks an "exodus" has implications that stretch far beyond concerns of structural formality. The strange and spectacular revenge that Strepsiades exacts fits neither the comic nor the tragic models. A comedy, for instance, requires a festive ending and while the scene of the conflagration must have been quite dramatic and fantastic to watch, it can hardly qualify as a celebration in any acceptable sense. On the other hand, a tragedy requires that the tragic hero accept his or her punishment and its essential, moral rectitude as what is "due" for his or her tragic flaw. However, in The Clouds, when the Chorus of Clouds condemns Strepsiades for his rash atheism and pronounce his tragic punishment as just, Strepsiades agrees and still pursues further violence: The Clouds ends in tragic overkill! Because of its failure to conform to either category, thus, The Clouds can comfortably be characterized as an atypical Aristophanic comedy.
