layman

This term describes an individual lacking specialized professional training or official status within a specific domain. It carries a neutral to slightly humble connotation, often used to emphasize the need for clarity or simplification when communicating complex ideas to a general audience. In ecclesiastical contexts, the word specifically distinguishes the general congregation from the ordained clergy. While the term is historically masculine, it is frequently used as a generic descriptor for any non-expert, though "layperson" is the common gender-neutral alternative.
