Questions & Answers about Nǐ shàngbān děi chuān lánsè de yīfu ma?

What does the modal 得 (děi) mean here, and how strong is it compared with 要 and 必须?

• 得 (děi) = have to/must (spoken, fairly strong, sounds like a personal or situational necessity).
• 要 (yào) = need to/going to; can mean obligation in context but is a bit softer and more general.
• 必须 (bìxū) = must; strongest and more formal/legalistic (rules, regulations). Examples:
• 你上班得穿蓝色的衣服。= You have to wear blue at work.
• 你上班要穿蓝色的衣服。= You need to/are supposed to wear blue at work.
• 你上班必须穿蓝色的衣服。= You must wear blue at work (strict rule).

How do I negate this idea? Is it 不得?

To negate a “must” as “not necessary,” use:

• 不用穿 / 不必穿 / 不需要穿 (don’t need to wear). If you mean “must not” (prohibited), use:
• 不能穿 / 不可以穿 (not allowed to wear), or formal 不得穿 (must not). Note: 不得 is not the simple negation of 得(děi); it means a prohibition.

Is this 得 the same as the one in degree complements like 走得快?

No. There are three common “de” particles:

• 得 (děi, 3rd tone): modal “have to” (this sentence).
• 得 (de, neutral) after verbs/adjectives for complements: 说得很快 (speaks quickly).
• 的 (de, neutral) for attributives: 蓝色的衣服 (blue clothes).
• 地 (de, neutral) for adverbials: 慢慢地走 (walk slowly).
