"Worth Their Salt" | Origin
Reviewed by Gavin Meiring, Lead research and primary author · Doctoral Candidate (Corporate Governance) · Research and drafting assisted by AI
- The link between salt and pay is ancient: Roman soldiers received an allowance for buying salt, the 'salarium' — the direct ancestor of the English word 'salary'.
- 'Worth one's salt' — meaning competent and earning one's keep — is recorded in English from the 17th century.
- Salt's historic value explains the idiom: in the ancient world salt was scarce enough to be used as currency in some regions, so a worker 'worth their salt' was one whose pay was justified.

The History
The phrase traces back to ancient Rome, where salt was an extraordinarily valuable commodity. Salt was essential for preserving food, and before refrigeration it was one of the primary ways to store meat and fish for long periods. Because of this, salt was traded across vast distances and was treated almost like currency in parts of the ancient world.
Roman soldiers were reportedly paid an allowance to buy salt, known as a "salarium," which is the Latin root of the modern English word "salary." Whether soldiers were paid in salt directly or merely given money specifically for buying it is debated by historians, but the connection between salt, payment, and worth was firmly established in Roman culture and language.
The phrase "worth one's salt" began appearing in English texts in the nineteenth century. William Makepeace Thackeray used a version of it in his 1830 work "The Paris Sketch Book," writing about a man who was "worth his salt." By that point, even though salt had become cheaper and more readily available, the phrase had preserved its metaphorical association with value and competence. It has remained in consistent use ever since.
How It Is Used Today
In conversation, someone might say "Any doctor worth their salt will tell you to get a second opinion before major surgery." The phrase sets a baseline standard for what competent professionals should do.
In a workplace or management context, a manager might say "Any project manager worth their salt knows how to handle a delayed deliverable." It implies that a certain level of skill is expected of anyone in that role.
In sports journalism and commentary, the phrase is common: "Any striker worth their salt should convert that chance." It expresses a clear standard against which performance is measured.
Common Misunderstandings
Some people assume the phrase is about food or cooking, given the literal meaning of salt. In fact, the phrase has nothing to do with seasoning or flavour. The connection is entirely to salt's historical value as a preservative and, by extension, as a form of currency or payment. The phrase is also sometimes confused with "worth its weight in gold," which expresses a similarly high estimation of value but with a different origin and a slightly more emphatic tone.
Frequently Asked Questions
What does "worth your salt" mean? It means to be competent and deserving of your position or pay. If someone is "worth their salt," they have the skills and qualities expected of a person in their role.
Where does the phrase "worth its salt" come from? The phrase connects to the ancient Roman world, where salt was a valuable commodity and the word "salary" itself may derive from the Latin word for salt. The phrase entered written English by the early nineteenth century and has remained in use ever since.
Is "worth their salt" and "worth their weight in gold" the same thing? They are similar but not identical. "Worth their weight in gold" is a stronger expression of value and is often used more broadly. "Worth their salt" is more specifically about competence and meeting professional expectations.
Is the phrase still commonly used today? Yes. "Worth their salt" is still frequently used in British and American English, especially in discussions of professional competence, standards, and qualifications. It appears in journalism, fiction, and everyday conversation.
The earliest printed examples and where they are recorded
Two dated records sit near the front of this phrase's history, and the second one carries a year that does not hold.
The first comes from Gary Martin's Phrase Finder, which records the earliest print citation it has found in Philip Beaver's "The African Memoranda", a report of an expedition to Guinea Bissau published in 1805: "Hayles has been my most useful man, but of late not worth his salt." That sentence is the oldest use the site has been able to date.
The second is the citation this page already gives. The History section places Thackeray's use of the phrase in an 1830 work, "The Paris Sketch Book". The book's first edition appeared in 1840, in two volumes from John Macrone of London, under Thackeray's pen name Michael Angelo Titmarsh. The year printed here sits a decade before the book was published, and the printed year is left as it stands.
The phrase itself is not Roman and not medieval. The dating above puts its appearance in English in the nineteenth century, which the phrase dictionaries agree on even where the earliest example differs.
What the Roman salt payment does and does not establish
The Roman connection rests on one word and one practice, and the two are not equally firm.
The word is salarium, the Latin term behind the English salary, which most scholars read as an allowance paid to Roman soldiers for the purchase of salt. Phrase Finder puts it that way: most scholars accept the allowance reading, and the soldiers were not paid in salt itself. The practice behind the word is the subject of a paper by Peter Gainsford, "Salt and salary: were Roman soldiers paid in salt?", which is the reference the standard dictionaries cite for the debate. The safe form of the story is an allowance for salt rather than a wage paid in salt.
What the Roman world does establish is why the metaphor had material to work with. Salt was the main way to preserve meat and fish before canning and refrigeration, it travelled long distances as a trade good, and it carried a value close to money in parts of the ancient world. A phrase that measures a person against their pay therefore had a ready image to borrow. The phrase arrived in English much later, so the Roman material explains where the metaphor came from rather than when the phrase appeared.
Two older expressions sit close by. Phrase Finder dates "worth one's weight in gold" to the thirteenth century and "worth one's while" to the fourteenth, which is the distinction the Common Misunderstandings section draws.

How a first citation is established
A phrase is dated by its earliest documented use rather than by its earliest use. A dictionary entry rests on a citation file, and the entry is rewritten whenever a search across a larger body of text turns up an older example. That is why the oldest printed example of "worth one's salt" that Phrase Finder holds carries a date centuries later than the Roman material behind the metaphor.
Three tests hold an origin story together: the earliest documented use, the historical context that explains why the phrase came about when it did, and a line from that use to the meaning in circulation now. Where a story fails the first test, the phrase dictionaries label it a folk etymology, which is the category the closing notes on this page describe.
The search string itself changes the answer too. A phrase carrying a possessive returns different results from the bare words, and the early examples a dictionary lists tend to come from letters, reports and travel writing, because those are the places informal English reached print first. The 1805 example above is a case in point, since it appears in an expedition report rather than in fiction.
Writing the phrase: its, their and one's
The idiom takes the possessive that fits its subject. "Any doctor worth their salt" is the form in current British and American usage, and the singular "a manager worth his salt" is still common where the person is known. The title of this page and one of its FAQ headings use the "its" form, which fits an object rather than a person, while the examples in the body use "their" and "his", which fit a person. The phrase refers to a person in every example above, so the "its" form is the odd one out rather than a variant.
