pronouns

 Mine, yours, his, hers, its, ours, theirs, and whose are the most common.

the pronouns used to show the possession i.e. my his her your our their and of course as suggested by "Phil Ammann."

Pronouns that indicate ownership are called Possessive Pronouns - they can act on their own or be used to describe a noun, for example:

i) (mine/yours, his/hers, ours/theirs) That car is theirs OR

ii) (my/your, his/her, its/our/their) That is their car. (Here the possessive pronoun - their -describes/modifies the noun - car.)

Possessive Pronouns also describe verbs ending in -ing that act as nouns, i.e. Gerunds.

For instance, "His (possessive pronoun) losing (gerund) the first race did not deter him from later victories."
