Morphology

lay + witness

The meaning 'a non-expert person who testifies' is directly derivable from combining 'lay' (ordinary/non-expert) with 'witness' (person who testifies). This adjective + noun composition transparently signals a witness who is not an expert, so a B1 learner who knows both words should understand it.

Etymology

The term lay witness comes from lay, meaning an ordinary person rather than a trained expert, and witness, meaning someone who saw an event. That's why a lay witness says what they 'personally saw' or experienced, not what an 'expert' would say.
