1. ## may not

Hi guys.
I'd like to ask You a question about modal verbs. I thought 'may' and 'might' are modals expressing probability, but recently I've learnt that 'may not' means the same as 'must not.' it confused me a little. Thus my question is: How to express, with modal verb, that it is possible that some event will not happen. Can I say: it may/might not happen? Or it is incorrect? If it is wrong, provide me with a correct version, please.
Kind regards,
Sebastian

Me too, Sebastian. Can you give us an example? Modals express both deontic [social] and epistemic [level of certainty] meanings. It sounds like someone might have confused the two.

Yes, you can use a negative may/might as in,

"It may/might not happen" but they wouldn't be all that common. Mostly, they'd be used as a mild denial of a positive may/might statement.

A: We'd better cancel the picnic. It may/rain.

B: It may/might not rain. Let's wait a bit longer before we decide.

Kind regards,
Sebastian

Seba,
Depending on use "may not" could mean either "must not" or "might not".
Examples: Seba: "May I have some cake?" Carl: "No you may not." in this case may not means that you do not have permission. However, in the sentence "I hope I go to Florida this year but I may not." may not means that it may or may not occur.
It is perfectly acceptable to use "it may/might not happen"

Hi Riverkid!
Well, I don't remeber the exact situation that made me so confused, so I can't write it to You. Shoud I retrieve it from my memory, I'll write it here And, of course, I thank both of You guys! You're more than helpful
Cheers.

I've been thinking about this a bit too and I can't imagine a situation where 'must' means 'may' for permission.

I don't believe that Carl's example shows this connection though I may well be missing something.

Again, I can't think of how we would use 'must not' to state 'one doesn't have permission'. Is there a meaning in English for a 'must' of permission? There might be, but it eludes me right now. Perhaps, Carl could show us one.

"No you may not" is close to "No you can not" in meaning.

How about: "You musn't go to school tomorrow. You're too sick."?
Maybe that's a bad example, but I believe "musn't" conveys here the meaning of lack of permission. Although, I know it is not the 'standart' way of expressing lack of permission. Comment on that Riverkid, please. I'd like to see Your point of view. All in all, You're the one who's spoken that language for ages and I'm just a student of a foreign language.
Seba
