Etymology

The word "granddad" is a compound formed from the familiar English words "grand" and "dad." The prefix "grand," derived from Latin grandis meaning "great" or "large," was adopted into English to indicate a relationship one degree further removed, as seen in "grandfather" and "grandmother." The second element, "dad," originates from the natural, reduplicative babbling sounds ("da-da") made by infants, which became a universal colloquial term for father. Thus, "granddad" literally and affectionately means "great father," combining a formal relational prefix with an intimate, familial noun to create a warm, informal term for a paternal grandfather.
