In the context of the television show “Young Sheldon,” the term “nibling” is a gender-neutral way to refer to a niece or nephew. It combines “niece” and “nephew” into a single term. The word is not commonly used in everyday language but has been adopted in some discussions about gender inclusivity, particularly when referring to the offspring of siblings without specifying their gender.
In “Young Sheldon,” which is a spin-off of “The Big Bang Theory,” Sheldon Cooper is portrayed as a child prodigy navigating life in Texas with his family. The show explores his relationships with his family members, including his siblings, which could lead to references to his niblings if the story progresses to include his nieces and nephews.
In summary, “nibling” is simply a term for the children of one’s siblings, and its usage highlights a contemporary shift toward more inclusive language.
