Other forms: grandchildren
A grandchild is the child of your own son or daughter. One generation further along.
English splits it by sex into grandson and granddaughter, and the plural grandchildren is used constantly by people of a certain age. The word is one word and the double d in granddaughter catches almost everybody out. A great-grandchild is the next step, and a family that reaches four living generations is worth a photograph. The matching words in the other direction are grandparent, grandmother and grandfather.
