great-grandmother
UK: ˌɡreɪt ˈɡrænmʌðə | US: ˌɡreɪt ˈɡrænmʌðər
n. the mother of one’s grandparent; a grandmother of one’s parent.
The word "great-grandmother" is a compound formed by combining "great" (indicating an additional generational layer), "grand" (denoting a familial hierarchy beyond immediate parents), and "mother" (the core term for a female parent). The prefix "great-" extends the generational scope, while "grand-" was historically used in Old French (grant) and Latin (grandis) to signify importance or seniority. The term reflects a logical, additive structure common in English kinship terminology.
