So last week, we did a post on how to say grandfather in Korean. So naturally, we had to do one on grandmother as well! Saying grandma follows the same standard as grandpa as there are slightly different ways to say it depending on if it’s your mother or father’s side and if you want to say it in a formal or informal way.
Keep in mind that for both grandma and grandpa, a standard 할머니/할아버지 can be used for both sides of the family. Adding the “외” is more academically correct in terms of studying.
