Grandson → It is formed from "grand" (from Old French *grand*, meaning large or great) and "son" (from Old English *sunu*, meaning male child). The word "grandson" refers to the male child of one's child, emphasizing the generational relationship as a great or larger connection to the family lineage.
Think of 'grand' meaning great and 'son' meaning male child — a grandson is a great connection to your family as the child of your child.
