stepuncle
A stepuncle is the husband of one's aunt or uncle, or the uncle of one's spouse. This means that a stepuncle is not related by blood to the person referring to them as such. The relationship is formed through marriage. For example, if a person's aunt remarries, the new husband of that aunt would be considered a stepuncle. Similarly, if a person marries someone who already has an uncle, that uncle would be their stepuncle. The term is less common than stepbrother or stepsister, as it often refers to a more distant familial connection. In some cultures, stepuncles may play a role in family gatherings or celebrations, but their specific role can vary widely. The term itself is a compound word, combining "step" to indicate a relationship formed by remarriage, and "uncle" to denote the familial position.
