“Niblings” is a term used to describe a person’s nieces and nephews collectively. The word is a gender-neutral alternative to more traditional terms such as “nephews and nieces” or “nieces and nephews.”

The term “nibling” was coined in the late 1950s or early 1960s, and it has since gained popularity as a way to refer to one’s nieces and nephews in a way that is more inclusive of non-binary and gender-nonconforming individuals.
The use of gender-neutral language has become increasingly important in recent years, as more people have become aware of the importance of inclusivity and diversity in language. Using gender-neutral terms can help to avoid excluding people based on their gender identity, and it can also help to promote greater awareness and understanding of issues related to gender and sexuality.
While some people may be unfamiliar with the term “niblings,” it is becoming more widely recognized and accepted as a way to refer to one’s nieces and nephews. In fact, some people have even begun using the term “nib” as a shorthand way to refer to a single niece or nephew.
Ultimately, the use of gender-neutral language is an important way to promote inclusivity and diversity in all aspects of society, and the term “niblings” is just one example of how language is evolving to better reflect the needs and experiences of people of all genders and backgrounds.
