Elicit vs. illicit: two words that sound alike, not the same

The short answer

Elicit and illicit sound similar but serve completely different roles in a sentence. Elicit is a verb meaning to draw out or bring forth a response, answer, or reaction from someone. Illicit is an adjective meaning illegal or not permitted, often describing behavior that breaks a rule, law, or moral code of some kind.

Since one word is a verb and the other is an adjective, checking how the word functions in the sentence is often the fastest way to confirm which spelling you actually need before you finish writing or publishing it for readers to see.

What each word means

Elicit means to evoke or draw out information, an emotion, or a reaction, usually through questioning or prompting. The teacher's question was designed to elicit a thoughtful discussion from the class about the assigned reading. Elicit is almost always followed by words like response, reaction, information, or answer, which signals its meaning.

Illicit describes something forbidden by law, rule, or custom, such as illicit drugs, illicit trade, or an illicit affair between two people. It functions only as an adjective, describing a noun rather than an action, so it will never appear with an -ed or -ing ending the way elicit routinely can.

Where the confusion comes from

Elicit and illicit are near-homophones, differing by only a single vowel sound at the start, which makes them easy to mishear in speech or mistype while writing quickly. Writers also sometimes assume both words relate to something being wrong or hidden, when in fact elicit is a completely neutral word about drawing out a reaction from someone.

Correct and incorrect examples

Use elicit when something produces a response, and illicit when something is against the rules or the law. Correct: the survey aimed to elicit honest feedback from employees. Not: the survey aimed to illicit honest feedback. Correct: police seized the illicit goods at the border. Not: police seized the elicit goods at the border.

• Correct: Her joke elicited a round of laughter.
• Not: Her joke illicited a round of laughter.
• Correct: The company was fined for illicit trading.
• Correct: Good questions elicit detailed answers.

A quick grammar check

Because illicit is only ever an adjective, it will sit directly next to a noun it describes, such as illicit substances or illicit gains. Elicit, being a verb, needs a subject performing the action and usually an object receiving it, such as the interviewer elicited a confession. Spotting this pattern helps even when the meaning feels unclear in the moment.

If you are unsure, try removing the word and asking whether the sentence still needs an action or a description. A missing action points to elicit, while a missing description points to illicit, since one performs and the other characterizes.

Remember it

Connect illicit with illegal, since both start with the letters i-l-l and both describe wrongdoing of some kind. Elicit, by contrast, shares its opening sound with elevate, and elevate involves bringing something up or out, much like elicit brings out a response. If the sentence needs a verb, elicit is your word.
