The deliberate explanation of a complex subject using everyday words and familiar concepts, avoiding jargon or technical terminology.
Linguistics
Semantic Notes
The phrase carries the implication that the original explanation was too technical or specialized for the intended audience. It often functions as a request ("Could you put that in layman's terms?") or as a descriptor ("He explained the theory in layman's terms."). The singular possessive "layman's" is standard, though "layperson's terms" is a gender-neutral modern variant.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or use. Both use the standard "layman's terms." The gender-neutral "layperson's terms" or "plain English" may be slightly more common in modern American publications due to sensitivity to gendered language.
Connotations
In both dialects, it connotes clarity, accessibility, and consideration for a non-specialist audience.
Frequency
Equally common and well-understood in both varieties. The core phrase is a standard lexical item.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating "layman" directly as "профан" (which implies ignorance) or "неспециалист" (clumsy). The standard translation is "понятным/простым языком" or "для неспециалиста." The phrase "обывательскими терминами" is incorrect and pejorative.
Common Mistakes
- Using the plural non-possessive 'layman terms' (incorrect). Confusing 'layman' with 'layabout.' Using it in overly formal contexts where 'non-specialist terminology' might be more appropriate.

Frequently Asked Questions
Historically, 'layman' was gender-neutral (from Old English 'leah' + 'man' meaning 'person of the people'), but in modern usage, it is often perceived as male-centric. In formal or sensitive writing, alternatives like 'plain language,' 'everyday terms,' or 'layperson's terms' are recommended.
No, this is a common error. The standard form is the possessive 'layman's terms,' meaning 'the terms of a layman.' 'Laymen terms' is grammatically incorrect.
They are very close synonyms. 'Layman's terms' explicitly references a non-expert audience. 'Plain English' is a broader movement advocating for clear, direct communication in all official and public documents, not just for non-experts.
Not at all. It is a polite and common way to indicate that you are not familiar with the specialist vocabulary of a field and would appreciate a simpler explanation. It shows engagement and a desire to understand.
