What is a nibling

A nibling is a colloquial or informal term used to refer to the niece or nephew of one's spouse. In other words, if someone is married, their spouse's niece or nephew would be their nibling. This term is not commonly used in everyday language, but it is a convenient way to describe this specific family relationship.

It's worth noting that the term "nibling" is not recognized by all dictionaries or language authorities, and its use is not widespread. However, it has been used in some online forums and social media platforms as a way to describe this specific family connection.

For those interested in learning more about family relationships and genealogy, I recommend checking out online resources such as FamilySearch.org or Ancestry.com, which provide a wealth of information on building and exploring family trees.
