Answer:
Hyperbole
Step-by-step explanation:
The hyperbole, also called auxese, is a figure of speech used in figurative language. This type of figure of speech represents an expression of dramatic exaggeration in the sentence. An example of this can be seen in the sentence shown in the question above, where the speaker exaggerates when stating that the teacher spoke non-stop, since this is not possible and that this represents an increased idea of how the teacher spoke, that is, an exaggeration.
