Finn
Hello! I’m Finn, with another pronunciation tip.
Today we're looking at 'must' and 'mustn't'.
First, mustn't.
You'll notice that the middle 't' is silent.
Mustn't, mustn't. Not musTn't, but mustn’t
Now, 'must'. When you say the word on its own, it has a 't' at the end. It's pronounced 'must'.
But when it's followed by a word which starts with a consonant, that sound disappears. Listen to this.
I mus(t) go
You mus(t) come
'Muss go'
'Muss come'
And one last tip, when it's followed by a word which starts with a vowel like 'open', listen to what happens.
I must open
You must arrive
The 't' is there, but it joins on to the word afterwards.
'Mus topen'
'Mus tarrive'
There you go. That's the pronunciation tip for today. Bye.
To do
Read these sentences. Practise saying them by yourself.
- You really must pay for that!
- You mustn't worry.
- You must arrive before 6am.
- You must offer me a higher salary!
- Mustn’t grumble.

Great! We must make sure you've learned all the grammar. Here’s 6 Minute Grammar.
Session Grammar
If you must do something, it is necessary for you to do it, but this is often your opinion or a rule that you have made yourself.
If you have to do something, it is necessary for you to do it. It’s a law, an obligation or a fact.
If you don’t have to do something, it isn’t necessary to do it, but you can if you want.
If you mustn’t do something, it means ‘don’t do it’. It is necessary not to do it.
