What does layperson mean?
A layperson is someone who does not have professional training in a particular field. The word is especially common in discussions of law, medicine, government, and other specialized institutions, where it distinguishes members of the public or untrained participants from qualified professionals. Its neutral sense can indicate that a person has no institutional connection to a field; in an adversarial context, however, it may suggest that their opinion or understanding is not professionally informed. A layperson is not necessarily inexperienced, uninformed, or incompetent. The term can be used to recognize the value of direct, practical knowledge and to ensure that decisions are not made solely by specialists. It is related to the older expression “layman,” but is often preferred when the gender of the person is unknown or irrelevant. In public institutions, panels and committees that include laypeople use the broader idea of ordinary citizens contributing to decisions that affect them.
nounA person who is not a member of a profession, profession, or other specialized field, especially one without professional training in law, medicine, or a similar discipline.
- A person who does not belong to a particular profession or specialized field and lacks formal training in it.

“Laypeople” is the standard plural. “Laypersons” is also used, especially in legal and formal writing, but is less common.

A layperson may lack professional credentials, but not wisdom: the word exists to ensure that specialist knowledge does not become the only voice in the room.

Where does layperson come from?
The word was formed by combining the established adjective “lay,” meaning nonprofessional or not belonging to a profession, with the neutral noun “person.” The compound belongs to a wider English pattern that uses gender-neutral terms for people in professional contexts. It developed alongside expressions such as “layman” and “laywoman,” although “layperson” does not mark gender and is therefore useful in institutional and public-facing language.
