Etymology
the word "grandniece" is a straightforward compound formed within english by combining the prefix "grand-" with the noun "niece." the prefix "grand-" originates from the latin adjective grandis, meaning "large" or "great," which entered english through old french. in the context of kinship terms, it was adopted to denote a relationship one degree further removed, such as a grandparent or grandchild. by attaching "grand-" to "niece"—a term itself descended from latin neptis via old french—the compound logically creates a term for the daughter of one's own niece or nephew, extending the familial line by one generation.
