The word “aunt” can be capitalized depending on how it is used in a sentence or title. When used generically in a sentence such as: “my aunt said to visit her,” then the word “aunt” is lowercase because it is a generic noun.
Correct: The other day I went shopping with my aunt.
However, when referring to an aunt by name such as “Aunt Audrey,” then the word aunt is capitalized because it is a part of the name so it becomes a proper noun. This is also true when asking a question of your aunt.
Correct: My Aunt Audrey is the best.
Correct: Can I go to the movies, Aunt?
