What figurative language is Penny bit into the ripe peach, its flesh giving way to a ruver of sweet juice

Hello. The phrase you show above presents the word "ruver", I believe that this was a typing mistake and the correct word is "river." In this case, the figure of speech used is called Hiperbole.

Explanation:

Hyperbole is the figure of speech that allows a sentence to exaggerate in terms of the intensity or quantity of something. In the sentence shown in the question above, we can see that the narrator states that when Penny bit the peach he can taste a river of juice. It is impossible for a peach to have a river of juice, but this exaggerated expression is used to show intensity and allow the reader to understand that the peach was very juicy, with a lot of juice in its pulp. In this case, the narrator is making use of the figure of speech called hyperbole.

i'm thinking it would be when compound subjects are joined by or, nor,either-or, neither-nor.
