In a way that is final, conclusive, and not able to be disputed or changed.
From Latin 'definitivus' meaning 'serving to limit' from 'definire' meaning to set bounds. The suffix '-ly' converts the adjective to an adverb. The word emphasizes clear boundaries and settled conclusions.
When you say something 'definitively,' you're drawing a clear line—the word literally means 'with definite boundaries.' That's why it sounds so authoritative; you're saying 'here's the fence, and nothing gets in or out to change this.'
