The word 'salary' comes from the Latin word for salt.

English “salary” descends from the Latin “salarium,” which itself derives from “sal,” the Latin word for salt. In the Roman world, salt was a valuable commodity used for preserving food, and “salarium” referred to an allowance or payment given to soldiers and officials.

Exactly what that payment consisted of has been debated by etymologists for a long time; the popular story that Roman soldiers were literally paid in salt is widely repeated but not solidly confirmed by historical sources, and many linguists consider it an oversimplified legend. What’s linguistically certain is the root connection itself: the everyday English word for a fixed wage traces directly back to salt, a reminder of how ordinary commodities can work their way permanently into a language’s vocabulary.
