Sage

Sage is a plant with soft, gray‑green leaves that are used as a cooking herb and sometimes as medicine. The word can also mean a very wise person.

The plant name comes from Old French *sauge*, from Latin *salvia*, from *salvus* 'healthy', because it was used as a healing herb. The meaning 'wise person' comes from a different Latin root, *sapere*, meaning 'to be wise or taste'.
