Grandmother → It is formed from "grand" (from Old French *grand*, meaning large or great) and "mother" (from Old English *modor*, meaning female parent). The word "grandmother" refers to a mother of one's parent, emphasizing her status as a great or significant maternal figure.
Think of 'grand' meaning large or great, and 'mother' as a female parent. This helps you remember that a grandmother is a great mother, specifically the mother of your parent.
