However, it's important to note that the term "Nana" can also refer to other individuals, like a chief or a king, and can even be used as a term of respect for elderly individuals in general.
If you need to be more specific about which grandmother you are referring to, you can use the following terms:
* "Nana maame": This means "mother's mother" or maternal grandmother.
* "Nana papa": This means "father's mother" or paternal grandmother.
Remember, it's always best to double-check with a native speaker for the most accurate and culturally appropriate way to use these terms.
