Usage
What does layman mean? Layman is used in a religious context to refer to a person who is a regular member of a religious congregation and not a member of the clergy—that is, a layman is someone who is not a religious official like a priest. The term clergy collectively refers to people who have been ordained or otherwise serve as religious leaders or officials, such as priests, rabbis, and nuns. People who are not part of the clergy can be called laypeople or collectively referred to as the laity. Layman and its plural form laymen specifically refer to men but are often used regardless of gender. However, the truly gender-neutral term layperson is also commonly used. Layman is perhaps even more commonly used outside of a religious context to refer to a person who is not a member of a particular profession or who is not an expert in or knowledgeable about a particular field. This sense of the word is used in the phrase layman’s terms, which means plain language that the average person can understand, as opposed to technical jargon that can only be understood by experts in the topic or those who are already familiar with it. When someone asks for an explanation in layman’s terms, they want it to be as simple and straightforward as possible, so that it can be understood by laymen—nonexperts. Example: She has built a career as a science writer by explaining complex topics in a way that is accessible to the layman.

Explanation
A layman might have a small amount of knowledge about something, but she isn't officially trained in the subject. If you need brain surgery, don't consult a layman; stick to a professional brain surgeon. Use the noun layman to describe your brother, who is an amateur bird watcher rather than a professional ornithologist. The word layman is most often used to contrast with expert or professional. Another way to use it is to distinguish between a member of the clergy — a priest or minister, for example — and an ordinary church member, or layman.
