granduncle
A granduncle is a male relative who is the brother of one's grandparent. This means a granduncle is a generation above one's parents, but two generations above oneself. To be more precise, a granduncle is the brother of a grandmother or a grandfather. The female equivalent of a granduncle is a grandaunt. The term is used in genealogical contexts and everyday conversation to describe this specific family relationship. In many cultures, granduncles are respected elders and can be a source of family history and tradition. The relationship is sometimes also referred to as a great-uncle, though granduncle is generally considered the more precise genealogical term.
