An aunt is a woman who is a sibling of a parent or married to a sibling of a parent. Aunts who are related by birth are second-degree relatives. Known alternate terms include auntie or aunty. Children in other cultures and families may refer to the cousins of their parents as aunt or uncle due to the age and generation gap.

Aunts by Generation

Additional termsEdit

  • A half-aunt is a half-sister of a parent.
  • An aunt-in-law is the aunt of one's spouse. An aunt-in-law can also be an aunt by marriage (female spouse of a relative)[citation needed].
  • A great-aunt[1][2]/grandaunt[3] (sometimes written grand-aunt[4]) is the sister of one's grandparent. Despite the popular usage of great-aunt, genealogists consider it more correct to use grandaunt for a grandparent's sister to avoid confusion with earlier generations. Similarly, the female siblings of one's great-grandparents are referred to as great-grandaunts.[5]

Genetics and consanguinityEdit

Aunts by birth (sister of a parent) are related to their nieces and nephews by 25%. As half-aunts are related through half-sisters, they are related by 12.5% to their nieces and nephews. Non-consanguineous aunts (female spouse of a relative) are not genetically related to their nieces and nephews.

Cultural variationsEdit

In some cultures, no single inclusive term describing both a person's kinship to their parental female sibling or parental female in-law exists. Instead, there are specific terms describing a person's kinship to their mother's female sibling, and a person's kinship to their father's female sibling.
