Words of art, also called terms of art, are words that have a specific meaning in certain professions, activities, sports, or subjects which may be different in layman’s English. Even though native English-speaking societies share a common language, there are a large number of specialized uses of words based on specific activities or professions. Each profession has a number of expressions and terms that are peculiar or idiomatic to it.
For an individual who works within a profession, those terms and expressions become words of art, which typically convey a different meaning from their lay usage, or which an outsider may not understand at all.
Put simply, words of art refers to terms that only people who specialize in a particular occupation or subject use and fully understand.
Words of art – legal profession
Often a court trial involves information and terms that are difficult or impossible for lay people to understand. So, expert witnesses are called to give evidence – to testify.
An expert witness is familiar with the words of art for a particular profession or subject. An accountant, for example, who is called to testify on a corporate fraud case, will be familiar with all the words of art used in accounting and company finance.

The expert witness typically explains the meanings of the relevant words of art to the jury, lawyers, and the judge.

Are words of art jargon?
“Words of art” and “jargon” are similar in that they both refer to specialized terminology used within a particular field or context. However, they have nuanced differences and are used in distinct ways:
Words of Art: This term is primarily used in legal contexts and refers to words and phrases that have a specific, well-established meaning within the legal profession. They are terms that might have an everyday meaning but take on a precise, specialized significance when used in legal documents or discussions.
- Example: “Tort” in everyday language might be unfamiliar or misunderstood, but in the legal world, it’s a well-known term referring to a civil wrongdoing that causes harm or injury, leading to legal liability.
Jargon: This is a broader term that encompasses specialized language used by professionals in various fields, not just law. Jargon terms are specific to certain professions, industries, or hobbies and are used to convey ideas with precision among people within that field.
- Example: In the world of computer programming, “API” stands for “Application Programming Interface,” a set of routines and protocols allowing different software entities to communicate with each other.
While “words of art” can be considered a form of jargon specific to the legal field, not all jargon is a “word of art.” Essentially, all “words of art” are jargon (within the legal profession), but not all jargon terms are “words of art.”
