IPA: /ɪˈlɪsɪtə/
KK: /ɪˈlɪsɪtər/
A person or thing that brings out a response or reaction.
The teacher used a question as an elicitor to encourage discussion among the students.
Elicitor → It is formed from "e-" (meaning out) and "licere" (meaning to permit or allow). The word "elicitor" refers to something that brings out or draws forth a response or reaction.
Think of something that 'permits' or 'allows' a response to come 'out' — that's why an elicitor is something that draws out a reaction.
