Possessive determiners indicate possession of someone, something, or some place. They use words such as myyourhisheritsour, and their before a noun. Possessive determiners are the same as possessive adjectives which are also used to show ownership.


Most of the words used as determiners are also used as pronouns. However, all the possessive determiners (and a few other determiners) cannot be used as pronouns as determiners are determiners and pronouns are pronouns. One has to be able to distinguish them in order to know how to use them correctly.
