What part of speech is a possessive noun classified as and what are the abbreviations used?

However, the possessive form of a noun acts as an adjective because it modifies another noun.

Abbreviations:

* N: Noun

* Adj: Adjective

Example:

* The dog's bone.

Here, "dog's" is the possessive form of the noun "dog" and acts as an adjective modifying the noun "bone".

Note: The possessive form of a noun can be indicated by adding an apostrophe and an 's' (dog's) or just an apostrophe (dogs') depending on whether the noun is singular or plural.
