Word Origin & Etymology

Borrowed in the early 15th century from Latin sanitas, meaning 'health of body or mind', derived from the adjective sanus ('healthy, sound'). Originally used in English for general physical and mental well-being, it narrowed in the 17th century to refer specifically to mental soundness.
