よくある間違い：
Learners sometimes use 'assert' for physical actions (e.g., *"He asserted the door"*), but it is only used for statements, beliefs, rights, or power. Another common mistake is using an infinitive instead of a clause, as in *"She asserted to be innocent"*; the correct pattern is *"She asserted that she was innocent"*.
