Dispel and expel both involve something going away, but they are not interchangeable.
Dispel means to drive away, clear up, or remove something that is usually abstract. You dispel doubts, fears, rumors, or confusion. Example: The new data dispelled concerns about the vaccine.
Expel means to force someone or something out of a place, group, or container. You expel a student from school, a member from a club, or air from the lungs. Example: The committee expelled the member for breaking the rules.
- Use dispel for ideas, feelings, or uncertainty.
- Use expel for people, objects, substances, or things being pushed out.
A quick memory tip: dispel clears the mind, while expel clears a place. If you are talking about doubt, fear, or confusion, choose dispel. If you are talking about removal from a school, group, or physical space, choose expel.
