In English grammar, a possessive determiner is a type of function word used in front of a noun to express possession or belonging (as in "my phone"). 

The possessive determiners in English are my, your, his, her, its, our, and their.

As Lobeck and Denham point out, there's some overlap between possessive determiners and possessive pronouns. The basic difference, they say, "is that pronouns replace full noun phrases. Possessive determiners, on the other hand, have to occur with a noun" (Navigating English Grammar, 2014).

Possessive determiners are sometimes called possessive adjectives, weak possessive pronouns, genitive pronouns, possessive determiner pronouns, or simply possessives.

Possessive Adjective or Determiner?

"The title  possessive adjective is actually more often used than possessive determiner but the latter is a more accurate description. Admittedly, in his car, the word his goes before the noun car and to that extent behaves as an adjective, but in *the his car (compare the old car) it shows itself not to be an adjective; it certainly doesn't describe the car itself." (Tony Penston, A Concise Grammar for English Language Teachers. TP Publications, 2005)

Possessive Pronouns and Possessive Determiners

  • "Most possessive determiners are similar to their corresponding possessive pronouns: her is a possessive determiner, while hers is a possessive pronoun. The possessive determiners his and its are identical to their corresponding possessive pronouns. The function in the sentence determines the part of speech. In The red Toyota is his car, his is a determiner because it's introducing the noun phrase car. In The red Toyota is his, his is a pronoun because it's functioning as a noun phrase. In The company made this pen, this is a determiner. In The company made this, it's a pronoun because it stands in place of a noun phrase."  (June Casagrande, It Was the Best of Sentences, It Was the Worst of Sentences. Ten Speed Press, 2010)
  • "[The] construction with the possessive pronoun [e.g. a friend of mine] differs from the alternative of possessive determiner + noun (e.g. my friend) mainly in that it is more indefinite. The sentences in (30) below illustrates this point:
(30) a. You know John? A friend of his told me that the food served at that restaurant is awful.
(30) b. You know John? His friend told me that the food served at that restaurant is awful.
  • "The construction with the possessive pronoun, in (30a), can be used if the speaker hasn't specified and doesn't need to specify the identity of the friend. In contrast, the construction with the possessive determiner, in (30b), implies that the speaker and listener both know what friend is intended." (Ron Cowan, The Teacher's Grammar of English: A Course Book and Reference Guide. Cambridge University Press, 2008)
