使唔使

Do You Need to …?

Level 2Sounds Like si2 m4 sai2

使唔使 (sai2 m4 sai2) means "do you need to...?" or "is it necessary to...?". It uses the standard Cantonese verb-not-verb question structure to ask about requirement or necessity.

How It Works

1. Structure and Attachment
As a modal auxiliary meaning "need to", place 使唔使 (sai2 m4 sai2) directly before a verb phrase or adjective phrase:

  • Verb Phrase: 使唔使 + Verb (e.g., 你使唔使睇醫生呀？ Do you need to see a doctor?)
  • Adjective Phrase: 使唔使 + 咁 + Adjective (e.g., 使唔使咁緊張呀？ Is there any need to be so nervous?)

Note on Nouns: 使唔使 does not attach directly to general nouns (e.g., you cannot say *使唔使水？). In expressions like 使唔使錢？ (Does it cost money?), 使 (sai2) functions as a main transitive verb meaning "to spend / cost", rather than a modal auxiliary.

2. Answer Asymmetry (Crucial Rule)
Because 使 (sai2) cannot function as an affirmative modal verb by itself in modern Cantonese, responses are asymmetrical:

  • Positive response ("Yes"): You must say 要 (jiu3) or 要呀 (jiu3 aa3). You cannot answer with *使!
  • Negative response ("No"): You say 唔使 (m4 sai2) or 唔使喇 (m4 sai2 laa3).

3. Pragmatic Uses

  • Checking Necessity: Asking if something is objectively required by rules or situation.
  • Polite Offers: Offering help smoothly (e.g., 使唔使幫手？ Do you need a hand?).
  • Rhetorical Exaggeration: Questioning if someone's behavior or reaction is over the top, usually paired with 咁 (gam3, so).

4. Texting Slang Note
While 使 is the correct traditional character, native speakers chatting online frequently type casual homophones like 駛 or 洗.

Examples (4)

  1. 你使唔使睇醫生呀？

    Do you need to see a doctor?

    Word by Word: you need-not-need see doctor [particle]?

    Asks whether seeing a doctor is necessary.

  2. 禮拜三使唔使返工啊？

    Do we need to work on Wednesday?

    Word by Word: Wednesday need-not-need return-work [particle]?

    Asks about objective scheduling requirements.

  3. 佢做咗經理啫，使唔使咁囂呀？

    He only became a manager, is it necessary to be so arrogant?

    Word by Word: he do [aspect] manager only, need-not-need so arrogant [particle]?

    Uses 使唔使 ＋ 咁 + Adjective as a rhetorical question expressing mild criticism.

  4. 使唔使我幫手呀？

    Do you need me to help out?

    Word by Word: need-not-need I help-hand [particle]?

    A standard, polite way to offer assistance.

Common Mistakes

  • Answering 'Yes' with 使 (sai2) or 使呀 (sai2 aa3).

    問：你使唔使幫手？ 答：使呀。
    問：你使唔使幫手？ 答：要呀。

    使 (sai2) is mostly heard in questions and in the negative 唔使. The usual way to say 'yes, you need to' is 要 (jiu3) or 要呀 (jiu3 aa3).

  • Using 使唔使 in formal Standard Written Chinese

    請確認我們使唔使出席會議。
    請確認我們是否需要出席會議。

    使唔使 is purely colloquial spoken Cantonese. In formal writing, use Standard Written Chinese expressions like 是否需要 (shì fǒu xū yào).
