Aunt

An aunt is a person who is the sister of a parent. A sister-in-law of a parent would be the person's aunt-in-law.

A great-aunt (sometimes called a grand-aunt) is the sister or sister-in-law of a grandparent.

The male equivalent of an aunt is an uncle, and the reciprocal relationship is that of a nephew or niece.

"Aunt" (or "auntie") may also be an honorific bestowed upon an individual of fictive kinship.
