To drive out, eject, or forcibly remove someone or something from a place or position.
From Latin 'expellere' (ex- 'out' + pellere 'to drive'). Though 'expel' is the standard modern form, 'expulse' is an older variant that survives primarily in legal and formal contexts.
While 'expel' became the dominant form, 'expulse' persists in very formal British legal documents and historical texts—it's a beautiful example of how Latin-based synonyms can coexist in English, with one becoming mainstream while its sibling remains in specialized registers.
