Etymology Origin:
The word convinced traces back to Latin convincere (to overcome decisively, prove wrong), combining con- (intensifier) and vincere (to conquer). Over time, its meaning shifted from "overcome by argument" to "persuade firmly." The past participle convinced retains the sense of a settled belief achieved through persuasion or evidence.
