Other forms: dispelled, dispelling, dispels
To dispel is to drive away doubts, fears, or myths. Dispel the rumour, dispel any doubt, dispel the myth.
It takes things of the mind rather than physical objects — you dispel a fear and not a crowd — and it implies scattering rather than defeating. Dispel the myth is the fixed phrase in explanatory writing. Note that the Latin is dis plus pellere, to drive, the same root as expel and propel.
