Hi Pupil,

As you have noticed, the English language is full of idioms - a fact that makes learning English both, interesting as well as challenging.
Fortunately enough, in Alan's tests you often can figure the meaning of an idiom:
If you take a look at the sentence in question you will find that a person who talks through their hat doesn't know what they talk about:

'Whatever you do take no notice of him because he's not thinking straight - he's talking through his hat.'

Would you explain this idiom "talking through smb?s hat" more exactly, may be in the another context or example?
in earlier explanation was used "talking through head? Is it a typo?

Thanks a lot
