Thinking about something again in a different way or reconsidering a previous decision or belief.
From the prefix 're-' (again) combined with 'thinking,' which comes from Old English 'thencan.' The word became more common in modern English as people increasingly needed to describe the process of reconsidering ideas.
Rethinking is actually how science works—scientists constantly rethink old theories when new evidence appears, which is why gravity was 'rethought' from Newton to Einstein, showing that admitting you were wrong is actually a sign of wisdom, not weakness.
