Etymology

Origin of nephew

1250–1300; Middle English neveu < Old French < Latin nepōtem, accusative of nepōs nephew, grandson; akin to Old English nefa, Dutch neef, German Neffe, Old Norse nefi; the pseudo-etymological spelling with ph has influenced pronunciation

Explanation

A nephew is the son of your sibling. This makes you the aunt or uncle of that nephew. While a mom, dad, sister, and brother are members of an immediate family, a nephew is part of your extended family because he's the son of a sibling. When brothers or sisters have male children, you become an aunt or an uncle to a nephew. If your nephew has a sister, she is your niece. Both niece and nephew originally meant "grandchild," but narrowed to their current meanings in the 1600s.
