คำอธิบาย
The word "yours" is a pronoun that shows possessiveness, but it's used independently as a post-modifier.
So in the sentence:
"That uncle of yours ought to see you through this."
The word "yours" is correct because it comes after a preposition ("uncle") and functions as a possessive pronoun.
