Sense: noun/1
Grandchild is the general term for any child of one's son or daughter, regardless of gender. Grandson and granddaughter specify the gender — use grandson for a boy and granddaughter for a girl. Grandkid is an informal, friendly alternative that works for any gender; you might hear 'My grandkids are coming over' in casual conversation but avoid it in formal writing. If you need to be gender-neutral and neutral in register, stick with grandchild or the plural grandchildren.

Etymology
The word grandchild is formed by combining grand- (from Old French 'grant', meaning 'big' or 'one generation removed') with child (from Old English 'cild', meaning 'infant or young person'). The prefix grand- was first used for family relationships in the early 1500s, following the same pattern as grandfather and grandmother. A grandchild is literally 'a child one generation larger' — that is, one step further from you in the family tree.
