Part 20 describes linguistic units from the letter to the sentence and discusses "simple" and "double" words, while the second-to-last section discusses irrational phrases, as when Ganymede is said to pour wine.  Part 6 notes that objects that are very large or small are not beautiful because they cannot be apprehended, and Part 15's treatment of character claims Odysseus's lament in Scylla is "inappropriate," while Iphigenia's prayer at Aulius is "inconsistent."  It also defines "complex action" as involving scenes of Reversal, Recognition, and Suffering in its sections on Plot, after arguing for the unities of action, time, and place.
