唔係（否則）

Or Else (Short Form)

Level 3Sounds Like m4 hai6

Use 唔係 (m4 hai6) at the start of a second clause to say 'otherwise' or 'or else'. It is the short, natural form of 'if not'.

How It Works

1. Function and Meaning
In spoken Cantonese, 唔係 (m4 hai6) is a common way to express 'otherwise' or 'or else'. It links two ideas: an action or condition in the first part, and a consequence in the second part. It implies: 'If you don't do [A], then [B] will happen.'

2. Sentence Structure
The standard pattern is:
[Action/Condition] + 唔係 (m4 hai6) + [Subject] + 就 (zau6) + [Consequence]

3. Common Variants
While beginners learn the full form 如果唔係 (jyu4 gwo2 m4 hai6), the 'if' (如果) is frequently dropped in casual speech. Other common variations include:

  • 唔係嘅話 (m4 hai6 ge3 waa2): Adds the conditional marker 嘅話 for clarity.
  • 要唔係 (jiu3 m4 hai6) / 一唔係 (jat1 m4 hai6): Often used when presenting an alternative suggestion or choice (e.g., 'Or else, we could...').

4. Distinguishing from 'To Not Be'
Context is key. If 唔係 (m4 hai6) is followed immediately by a noun (e.g., 佢唔係醫生 - He is not a doctor), it is the negated copula. If it sits between two full clauses, it means 'otherwise'.

Examples (4)

  1. 快啲啦，唔係就遲到㗎喇！

    Hurry up, or else we'll be late!

    Word by Word: Fast a-bit [particle], not-is then late-arrive [particle] [particle]!

    Here, 唔係 (m4 hai6) introduces the consequence of not hurrying. Note the use of 就 (zau6) to link the result.

  2. 你一定要帶遮，唔係嘅話就會淋濕晒。

    You must bring an umbrella, otherwise you will get completely soaked.

    Word by Word: You must-certainly need bring umbrella, not-is if then will soak-wet all.

    This example uses the variant 唔係嘅話 (m4 hai6 ge3 waa2), which adds 嘅話 (ge3 waa2) to explicitly mark the 'if' condition. 晒 (saai3) emphasizes 'completely'.

  3. 好彩你醒我咋，唔係我就唔記得咗喇。

    It's lucky you reminded me, otherwise I would have forgotten.

    Word by Word: Good-luck you remind me [particle], not-is I then not remember [aspect] [particle].

    This shows 唔係 (m4 hai6) used in a past-tense hypothetical context. 咗 (zo2) marks the completed state of forgetting.

  4. 一唔係我哋去食日本菜囉。

    Or else we could go eat Japanese food.

    Word by Word: One not-is we go eat Japan food [particle].

    The variant 一唔係 (jat1 m4 hai6) is used here to suggest an alternative option or a 'plan B'.

Common Mistakes

  • Omitting the adverb 'zau6' (then) in the second clause.

    快啲啦，唔係遲到。
    快啲啦，唔係就遲到。

    In Cantonese, 唔係 (m4 hai6) and 就 (zau6) work as a pair. Leaving out 'zau6' makes the sentence sound abrupt and less natural to native ears.

  • Placing the subject before 'm4 hai6'.

    你快啲，你唔係就遲到。
    你快啲，唔係你就遲到。

    As a conjunction meaning 'otherwise', 唔係 (m4 hai6) should come at the very start of the second clause, before the subject.

唔係（否則）Level 3Or Else (Short Form)

Learn This First

To understand the short form of 'or else' (唔係), learners need to be familiar with the basic negation of the verb 'to be' and how the particle '就' functions to link a condition to its result in the second clause of a sentence.
