That's a better start, Mohanand,
Just one suggestion: it's better to mark the idiom you are introducing in some way or another. You can use bold, italic fonts, or list them using the numbers, or
simply draw a seperation line between each two idioms. I'm looking forward to reading the rest of the idioms you have up your sleeves.
Cheers,
