You've heard Romans were 'paid in salt'. That's only half true.

The story sounds perfect: Roman soldiers, marching through the ancient world, receiving their wages in pouches of salt. It gets repeated in business books, TED Talks, and office small talk. The problem is that the historical record is considerably messier.

The Latin word 'salarium' does derive from 'sal' — salt. Pliny the Elder mentioned the connection in his Natural History, written around 77 AD. But what exactly that connection was is where the legend outpaces the evidence. The most defensible reading is that soldiers received a 'salt allowance' — an extra stipend to purchase salt — rather than salt itself handed out as wages.

Salt was genuinely precious in the ancient world: a preservative, a flavoring, a strategic resource. Roman roads were built partly to move it. The Via Salaria, one of Rome's oldest roads, gets its name from the salt trade. So a salt-linked payment made real economic sense.

By the time 'salary' entered English in the 13th century, via Old French 'salaire', it simply meant a fixed periodic payment. The salt had become a metaphor long before anyone thought to question whether it was ever literal.

The phrase 'worth his salt' — meaning competent, deserving of pay — survives in English to this day. The salt is long gone from the paycheck. The word quietly carries it anyway.
