salary: [14] Salary goes back to a Latin word that originally denoted an ‘allowance given to Roman soldiers for buying salt’ (salt being in former times a valued commodity, over which wars were fought, rather than taken for granted as it is today). This was salārium, a derivative of sāl ‘salt’. It soon broadened out to mean ‘fixed periodic payment for work done’, and passed in this sense via Anglo-Norman salarie into English. => salt[salary etymology, salary origin, 英语词源]
