To make someone believe that something is true or to persuade them to do something. It usually involves giving reasons, evidence, or emotional appeals.
From Latin *convincere* 'to prove, overcome', from *con-* 'completely' and *vincere* 'to conquer'. The idea is overcoming someone’s doubts with proof or argument.
To convince someone is literally to 'win over' their mind—same root as 'victory.' Facts help, but people are often convinced by trust and emotion just as much as logic. Real persuasion usually feels like guiding someone, not beating them in a debate.
