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.
