Which idioms dictionary shall I buy?

[heather]

Hi, Could you give me some advice to buy a good idioms dictionary! English is not my first language. Idioms for me is a big task to learn. How can I learn them? Thanks!

You don`t need to buy a dictionary of idioms.
See the following:
http://www.idiomsite.com

http://idioms.thefreedictionary.com/bacon
and many others..
or ,search the web for "ESL grammar exercises on idioms". I`m sure you`ll find lots of lists and exercises on English idioms.

If you want to buy one, the Cambridge dictionary is good.

Thanks! By the way what is different between Colloquialisms and idioms?

A colloquialism is just everday language, not formal, while an idiom is a phrase whose meaning isn't obvious from the meanings of the words that make it up:
Fiver (five pounds)- colloquial language, but not an idiom
I'll eat my hat- an idiom, whose meaning has nothing to do with eating hats.
