Grammar - Using "pa" for possessive pronouns

Yes, "pa" indicates the negative in Haitian Creole.
But, the word "pa" also have other definitions/roles in Creole.

And one of them is to indicate the possessive pronouns.

Mine

Pa mwen (uncontracted)

Pa m (contracted)

Yours

Pa ou (uncontracted)

Pa w (contracted)

His/hers

Pa li (uncontracted)

Pa l (contracted)

Ours

Pa nou (uncontracted)

Pa n (contracted)

Theirs

Pa yo

Examples:

1. This is mine.

Sa se pa mwen.

or

Sa se pa m.

2. The house is yours.
Kay la se pa ou.
or

Kay la se pa w.

3. This is yours.
Sa se pa ou an*.
or

Sa se pa w la*.

* Sometimes you'll see a definite article after the possessive pronoun.

The definite articles will follow a set of rules.  See #3 & #4, the sentences are the same, except that one has a contracted pronoun and the other one does not.  The Creole definite article will change according to the word it follows.

4. This is mine.

Sa se pa mwen an*.

Sa se pa m nan*.

5. This is not mine.
Sa se pa pa mwen an.

Sa se pa pa m nan*.

In example #5, see how the first "pa" indicates the negative, and the second "pa" does not.

6. This is my own food.
Sa se manje pa mwen an.

Sa se manje pa'm nan.

7. Don't sit here. This is my own chair.

Pa chita la. Sa se chèz pa mwen.

Pa chita la. Sa se chèz pa m.

8. Are these your kids?

Eske sa yo se timoun pa ou yo?

Eske sa yo se timoun pa w yo?
