得: Strong Practical Obligation in Chinese
得
得, pronounced děi here, marks a strong obligation arising from rules, circumstances, or practical necessity. It stands before the action that must happen. Its ordinary negative counterpart is 不用 or 不必, not 不得; 不得 instead expresses prohibition, so learners must keep obligation and prohibition distinct.

Read the structure
得, pronounced děi here, marks a strong obligation arising from rules, circumstances, or practical necessity. It stands before the action that must happen. Its ordinary negative counterpart is 不用 or 不必, not 不得; 不得 instead expresses prohibition, so learners must keep obligation and prohibition distinct. Keep the model Subject + 得 + Verb phrase visible while you compare each sentence.
我今天得早点儿回家。
I have to go home early today.
Choose the right context
State something circumstances require: 我得回家了。 Give a firm practical reminder: 你得带护照。 Describe a duty that cannot reasonably be skipped.
再忙也得吃饭。
However busy you are, you still have to eat.
Respect the boundary
Do not read this modal as dé or de. Do not negate obligation with 不得; that means must not. Do not place 得 after the action it governs.
我今天得了早点儿回家。
(I have-to-le go home early today.)
Repair the pattern
了 is inserted after the modal: Modal 得 directly precedes the required action; perfective 了 cannot attach to this modal. 得 is stranded after the negated action: To deny necessity, put 不用 or 不必 before the action; 不来得 is not a modal-negation pattern.
我今天得早点儿回家。
Use the repaired structure without changing the intended meaning.
