‘干娘’ (gān niáng) literally combines ‘干’ (gān), meaning ‘fictive’ or ‘ritual’, and ‘娘’ (niáng), meaning ‘mother’. Together, they denote a woman who has formally assumed the role of a mother in a non-biological, symbolic relationship—most commonly as a godmother. This bond is typically established through a traditional ceremony, often during childhood, and carries expectations of emotional support, moral guidance, and sometimes material care.

The term reflects Chinese kinship practices that extend family beyond blood ties. While historically tied to Daoist or folk religious rites, today ‘干娘’ is used more broadly in secular contexts—such as when a respected elder woman takes on a mentoring or protective role toward a child. It implies warmth, trust, and lifelong affection, distinct from formal titles like ‘老师’ (teacher) or ‘阿姨’ (auntie). The relationship is reciprocal: the child may address her as ‘干妈’ (gān mā) in informal speech, and she may refer to the child as ‘干儿子’ or ‘干女儿’.
