Misuse of these two words is rare, but they’re worth a second look.

Problem:
The words “elicit” and “illicit” are not synonyms.

Explanation:
The primary definition of the verb “elicit” is to evoke or draw out. For example, elicited a response with a huge lie would be an appropriate use of the verb. The popular definition of the adjective “illicit” is disapproved for moral reasons. For example, an illicit association with her student would be an appropriate use of the adjective.

The challenge with these two words is that they sound fairly alike, especially when speakers are careless with pronunciation. Careless pronunciation by speakers seems to lead to misuse by those listeners who are ignorant that these are two distinct words.

Solution:
Use “elicit” when you want to refer to evoking or drawing out; use “illicit” when you want to label something as immoral or unlawful.
