The plural form of "wolf" is "wolves". This is because "wolf" is a noun that describes a single animal, and when we want to describe more than one of these animals, we use the plural form "wolves". In English, many nouns have irregular plural forms, and "wolf" is one of them. Other examples of irregular plural forms include "sheep" (which becomes "sheep") and "fish" (which becomes "fish"). It's important to remember these rules so that you can correctly conjugate and use verbs in the plural form when describing multiple animals or objects of different kinds.
