A medical procedure that involves stitching the labia together to prevent sexual intercourse, often associated with extreme forms of female genital mutilation.
Infibulation is a practice that has serious health implications for women.
Infibulation is formed from "in-" (meaning in or into) and "fibula" (from Latin, meaning a clasp or brooch). The term refers to the act of fastening or securing, particularly in a medical context where it involves the insertion of a device to prevent sexual intercourse or childbirth.
Think of 'fastening something in' ('in-') with a 'clasp' ('fibula') — that's why infibulation refers to securing in a medical sense.
