We use determiners to express the reference of a noun in a given context. They tell us if the noun is general or specific.
Specific determiners:
The definite article: The.
Possessives: My, your, his, her, its, their, our.
Demonstratives: This, that, these, those.
Interrogative: Which.
We use specific determiners when we believe the listener/reader knows exactly what we are talking about.
Examples:
Do you want the ketchup?
Look at those lovely dogs.
Thanks for your present.
This is my computer.

General determiners are: A, an, any, another, other, what
_We use general determiners when the listener doesn’t know what we are talking about. We can use an uncountable noun or a plural noun with no.
