What does dispel mean?
Dispel is a formal verb meaning to make something — usually intangible — disappear entirely. It most often takes fears, doubts, worries, myths, or suspicions as its object: a reassuring statement dispels anxiety, and solid evidence dispels rumor. The word carries a sense of active, decisive removal rather than passive fading, implying that whatever is dispelled existed firmly enough to need driving out. Though it can occasionally describe physical phenomena, such as sunlight dispelling fog, its modern use is overwhelmingly abstract and figurative. Dispel entered English in the early seventeenth century from the Latin dispellere, formed from dis- ("apart") and pellere ("to drive"), making it a sibling of expel, repel, propel, and compel. It remains a favorite of journalists, scientists, and public figures precisely because it conveys authority: to dispel a misconception is not merely to question it but to banish it conclusively.

Etymology of dispel
Dispel comes from the Latin verb dispellere, meaning "to drive apart" or "to drive away," formed from the prefix dis- ("apart, asunder") and pellere ("to drive, thrust"). It entered English in the early seventeenth century, initially carrying both literal senses of driving something away and figurative senses of eliminating beliefs or emotions. Over time the figurative sense became dominant, so that today the word almost exclusively governs abstractions like fears and doubts. It shares its Latin root with a productive family of English words including expel, repel, propel, and compel.
How dispel is actually used
"Dispel" is somewhat formal and typically takes abstract objects — fears, doubts, myths, rumors, illusions. It is rarely used for physical objects except in figurative contexts like light dispersing darkness.
Easily confused with dispel
