What are definite and plural determiners?

Definite determiners are used to specify a particular noun and indicate that the noun is known or previously mentioned. Examples of definite determiners include "the" and "this."

Plural determiners, on the other hand, are used to indicate that the noun refers to more than one person, animal, thing, or concept. Examples of plural determiners include "some," "many," and "several."
