* Chaayan (ചായൻ): This is a slightly more formal way to refer to an uncle.

* Mama (മാമ): This term is used for the brother of one's mother.

* Kaka (കക): This term is used for the brother of one's father.

* Achan (അച്ഛൻ): This is a more respectful term, meaning "father", but can also be used to refer to an uncle who is older and respected.
