Is grandpa or grandfather capitalized?

The word “grandpa” or “grandfather” can be capitalized depending on how it is used in a sentence or title. When used generically in a sentence such as: “my grandpa said to visit him,” then the word grandpa is lowercase because it is a generic noun.

Correct: My grandpa is the best.
Correct: My grandfather loves me.

However, if you are addressing your grandpa directly, such as when asking a question, then you should capitalize the word grandpa.

Correct: Can I go to the movies, Grandpa?
Correct: Can I go to the movies, Grandfather?

The same holds true for any other names you might call your grandfather such as “papa” or “papap.”
