What is what do you call your grandma sister?

In many cultures, the term for your grandma's sister depends on the specific family dynamics and location. Here are some common possibilities:

• Great-Aunt: This is perhaps the most universally understood and accepted term. She is the sister of one of your grandparents.

• Grand-Aunt: This term is used interchangeably with great-aunt in many regions. The sister of your grandma.

• Aunt: In some families, particularly if your grandma and her sister were particularly close to you, you may simply refer to her as "Aunt" followed by her name.

The specific term used often comes down to family tradition and preference.
