Make sure you start and end every conversation in a correct way. Try to prevent the conversation from stalling (getting stuck).
If you don’t understand what the other person is saying, you can:
1 say you don’t understand something:
I’m sorry, but I don’t understand. / Could you repeat that, please? / I don’t know what that means.
2 ask for an explanation:
What does that mean? / What does it look like? / Can you describe it? / Can you give me an example?
If you don’t know a word, you can:
1 describe what something looks like:
It looks like a mouse, but it’s bigger. (rat)
2 explain what something is used for:
You can put tea or coffee in it to keep it hot. (thermos)
