Use elicit (a verb) to mean to draw out or provoke a response (elicit a reaction). Use illicit (an adjective) to mean illegal or forbidden (illicit drugs).
The Core Difference
“Elicit” is a verb meaning to bring out, evoke, or draw out information, a reaction, or a response, usually through questioning or a particular stimulus: elicit a response, elicit information.
“Illicit” is an adjective meaning not permitted by law, rules, or custom — illegal or forbidden: illicit trade, an illicit affair, illicit substances.
- verb, draw out a response → elicit: elicit feedback, elicit a smile
- adjective, illegal/forbidden → illicit: illicit goods, an illicit deal

Frequently Asked Questions
What is the fastest way to tell elicit from illicit?
“Elicit” is always a verb meaning to draw out a response. “Illicit” is always an adjective meaning illegal or forbidden. Link “illicit” to “illegal” since both start with “ill-”.
Can illicit ever be a verb?
No — “illicit” is only ever an adjective, describing something forbidden. Any verb meaning to provoke or draw out is always “elicit”.
What does elicit a response mean?
It means to successfully provoke or obtain a reaction, answer, or reaction from someone, often through a specific question, action, or stimulus.
Is illicit the same as illegal?
They are closely related but not identical — “illicit” can describe something forbidden by law, morality, or custom (an illicit affair may not be illegal, just socially disapproved), while “illegal” specifically means against the law.
Why do these words sound so similar?
“Elicit” and “illicit” are pronounced almost identically in fast speech, both starting with a short vowel sound followed by “-licit”, which is exactly why they are frequently confused in writing despite having completely unrelated meanings.
Is solicit related to elicit or illicit?
“Solicit” (to ask for or seek something, often persistently) shares the Latin root “licere” (to be permitted) with “illicit”, though its meaning of “to request” is functionally closer to “elicit” in everyday use, despite the different root connection.
Can elicit describe negative reactions too?
Yes — “elicit” is neutral about whether the response is positive or negative: you can elicit laughter, elicit criticism, or elicit sympathy.
Is this pair commonly tested in advanced vocabulary sections of exams?
Yes — elicit/illicit is a frequently tested pair in advanced English exams (CPE, IELTS band 7+) because the words are phonetically similar but grammatically and semantically unrelated.
Can illicit describe a relationship?
Yes — “illicit” often describes a forbidden romantic or sexual relationship, as in “an illicit affair”, meaning one that breaks social or moral rules, not necessarily the law.
What tense forms does elicit take?
As a regular verb, “elicit” follows the standard pattern: elicit, elicits, elicited, eliciting, as in “the question elicited a laugh from the class.” “Illicit” never changes form, since it is only ever an adjective.
