Nibling
（重定向自Grandnephew）
A nibling is the offspring of one's sibling, i.e. a nephew or niece. It is a neologism first used in 1951 to refer to a niece or a nephew, or in other words, the child of one's sibling. The term is gender-neutral and provides convenience for referring to a mixed group of nieces and nephews. "I bought my niblings a board game for Christmas."
