An idiom is a group of words whose meaning in everyday speech and writing is different from what you would expect.. The words are not literally true. Example:
to paddle your own canoe doesn't mean that you are really in a canoe. It means that you can do things for yourself.

A Explain in your own words what these well-known idioms mean:

1) It is raining cats and dogs.
2) We have sent him to Coventry.
3) I am trying to make both ends meet.
4) He is sitting on the fence.
5) I've got a bone to pick with you!
6) He has turned over a new leaf.
7) She is blowing her own trumpet.
8) They paid through the nose for it.
9) You are flogging a dead horse.
10) I can smell a rat.
