What does layman mean?
A layman is a person who is not an expert or specialist in a particular subject. The word is especially useful when discussing a technical, legal, medical, or academic topic from the perspective of an ordinary reader or nonexpert. Expressions such as "a layman's guide" emphasize making specialized information accessible to the general public. Although "layperson" is often a more formal and inclusive alternative, "layman" remains established in general English. In religious contexts, a layman may also mean a member of the laity, in contrast to clergy. The word can carry a slightly traditional or gender-marked tone because of its generic use of "man," so "layperson" is frequently preferred when inclusiveness matters.

Where does layman come from?
The word combines the Middle English adjective "lay," meaning amateur, untrained, or belonging to the laity, with "man." Its development reflects the longstanding distinction between people trained in a profession or field and those who are not. The related word "layperson" was created in the 20th century as a more explicit and inclusive alternative.
