Possessive pronoun

Possessive pronouns indicate the possession of something. In English grammar, there are two fundamental ways of using them – either similar to a noun or similar to an adjective. Compare:

• On the one hand, possessive pronouns can be used adjectivally (see the use of adjectives for details) in combination with a noun.
• On the other hand, they can be utilised substantivally if the corresponding noun is mentioned elsewhere in the same sentence, in a previous sentence, or in a subsequent one.

Notice: In contrast to some other languages, (such as German, for example) in English, possessive pronouns are not inflected, which means that their form never changes whatever noun is referred to.
