kinswoman

This term specifies a female relative, carrying a formal or archaic tone that suggests a strong emphasis on lineage and ancestral bonds. It is rarely used in casual modern conversation, where "relative" or "cousin" is preferred, but it remains common in historical narratives, legal documents regarding inheritance, or genealogical studies.

Because it is a gender-specific noun, it functions as the female counterpart to "kinsman." It describes a relationship based on kinship, whether through direct blood descent or the legal ties created by marriage.
