Your aunt's husband is your uncle.
Essentially, the man your aunt is married to holds the position of your uncle within your family structure. This is a common and straightforward familial relationship. Whether your aunt is your mother's sister, your father's sister, or related through marriage, her husband will always be considered your uncle.
Here's a breakdown:
- Aunt: Your parent's sister (or sister-in-law).
- Uncle: The husband of your aunt.
Therefore, the relationship is clearly defined within family kinship.
