The word 'salary' comes from salt — Roman soldiers were sometimes paid in it
The Latin word 'salarium' (salary) likely derives from 'sal' (salt). Salt was enormously valuable in the ancient world — it was the primary way to preserve food before refrigeration, and controlling salt supplies meant controlling armies and populations. The expression 'not worth his salt' comes from this era. The city of Salzburg in Austria literally means 'Salt Fortress'. Salt taxes have caused revolutions — Gandhi's famous Salt March was a protest against British salt taxes.
Every time you receive a paycheck, you're using a word that encodes an ancient economy where a mineral was literally currency.
