不得不
HSK 4- Modal verbs
Structure (结构 jiégòu)
Meaning (意思 yìsi)
不得不 expresses being compelled to do something due to circumstances, with no other choice available.
Explanation (解释 jiěshì)
不得不 (bù dé bù) means "to have no choice but to," "to be forced to" — expressing that one must do something reluctantly due to external circumstances, with no other option available.
It emphasizes unwillingness or compulsion, unlike 必须 (bìxū), which typically indicates necessity or obligation. For example, 我必须努力学习 (I must study hard) reflects a personal sense of need, whereas 考试要到了，我不得不学习 (The exam is coming, so I have no choice but to study) conveys being compelled by the situation.
