Etymology

The word "mate" traces back to Middle Low German māt (companion, friend), which entered English via Middle Dutch māte. It originally referred to a shared meal companion, reflecting the social bond of eating together. Over time, it broadened to denote friendship or partnership, retaining its core sense of camaraderie. In British English, it became a casual term for "friend," while in biological contexts, it evolved to describe pairing for reproduction.
