未必
Not Necessarily
Use 未必 (mei6 bit1) before a verb or adjective to say that something is 'not necessarily' true. It is a polite way to express doubt without a flat denial.
How It Works
1. Sentence Position
未必 (mei6 bit1) is an adverb and must be placed before the predicate (the verb or adjective).
Pattern: [Subject] + 未必 + [Verb/Adjective]
2. Tone and Nuance
This expression is very common in both spoken and written Cantonese. It sounds slightly more educated or professional than the purely colloquial 唔一定 (m4 jat1 ding6), but it is perfectly natural in daily conversation. It is often used to politely disagree or to point out exceptions.
3. Pairing with the Copula
A very common construction is pairing 未必 with the verb 係 (hai6) to say "it is not necessarily the case that...".
Example: 佢未必係好人 (keoi5 mei6 bit1 hai6 hou2 jan4) — "He isn't necessarily a good person."
4. Comparison with other negators
- 唔會 (m4 wui5): 'Will not' (Definite denial)
- 未必 (mei6 bit1): 'Might not / Not necessarily' (Uncertainty)
5. Standalone usage
In conversation, you will often hear it paired with sentence-final particles like 㗎 (gaa3) or 喎 (wo3) to soften the tone: 未必㗎 (mei6 bit1 gaa3) — 'Not necessarily, you know!'
Examples (4)
- 佢未必肯幫你。
He might not necessarily be willing to help you.
Word by Word: He not-necessarily willing help you.
未必 (mei6 bit1) is placed before the auxiliary verb 肯 (hang2 - willing) to show uncertainty about his willingness.
- 貴嘢未必好。
Expensive things aren't necessarily good.
Word by Word: Expensive things not-necessarily good.
Here, 未必 (mei6 bit1) modifies the adjective 好 (hou2 - good) to challenge a common assumption.
- 噉又未必喎!
Well, that's not necessarily the case!
Word by Word: That also not-necessarily [particle]!
This is a common idiomatic rebuttal. The particle 喎 (wo3) adds a sense of 'noting a different reality' to the disagreement.
- 聽日未必落雨。
It might not necessarily rain tomorrow.
Word by Word: Tomorrow not-necessarily fall rain.
Used here to express a lack of certainty regarding a future event (weather).
Common Mistakes
Using 未必 in an A-not-A question format.
未必唔未必呀?係咪一定㗎?You cannot use the A-not-A pattern with 未必. To ask 'Is it necessarily...?', use 係咪一定 (hai6 mai6 jat1 ding6).
Placing 未必 after the verb.
佢知未必。佢未必知。Like most Cantonese adverbs, 未必 (mei6 bit1) must come before the verb it modifies.
How It Connects
Learn This First
To understand '未必' (not necessarily), you first need to be familiar with basic negation in Cantonese, particularly the marker '未'. It is also helpful to understand how Cantonese expresses possibility and probability using words like '可能' (maybe), as '未必' functions as a way to weaken a claim by suggesting that the opposite is possible.
- 未Not Yet
The word '未必' (mei6 bit1) is a compound where '未' (mei6) provides the core sense of 'not yet' or 'not having occurred', which is essential for understanding the negative aspect of the claim.
Level 1 - 可能Maybe
Understanding '未必' requires a grasp of epistemic modality (possibility vs. certainty), which is first introduced through the pattern '可能' (maybe).
Level 2 - 唔係(否定整句)Is Not / It's Not That
Learners should understand how Cantonese uses negative markers to qualify statements or deny specific assertions before learning the more nuanced weakening of a claim provided by '未必'.

一定 (jat1 ding6) means 'definitely'; 未必 is its logical opposite ('not necessarily').
Level 2 - 唔會Won't / There's No Way
唔會 (m4 wui5) is a strong 'will not,' whereas 未必 is a weaker 'might not.'
Level 2 - 唔Not (General Negation)
The basic negator; 未必 is a more nuanced, modal version of negation.
Level 1 - 喎 (wo3)Noteworthy News
Often used with 未必 to highlight a surprising or contrary opinion.
Level 2 - 㗎 (gaa3)Fact Plus Reminder
Frequently follows 未必 to state a general truth or fact about uncertainty.
