使い分け解説:
- 替える: Emphasizes replacing one thing with another, often of the same kind (e.g., changing clothes, batteries, seats). Differs from 変える (to change generally) and 換える (to exchange, especially money).
- まんまと: Implies something worked out perfectly, often for the speaker's benefit and sometimes at another's expense, or a trick was pulled off. Can suggest success achieved deceptively.
