Best list of idioms?

You might want to check Manhattan GMAT SC book. There is one chapter dedicated to Idioms. In general, I think Idioms are not that difficult to find - I usually spot most of them now even though I am a not a native english speaker. I agree with Rhyme that they should not be remembered for the most part (although there are few which look and sound wierd enough to remember).

Came across this as well:

Although the site is useless, I think this idiom list is quite good.

You have to be very careful using idiom list only use reputed material such as PR or manhattan GMAT. Manhattan GMAT is good one.

Particularly, be very careful with prepositional idioms. Lot of lists on web contains widely used prepositional phrases but their may be some obscure use which may be ignored for ex. ‘centers on’ is correct so does ‘centers upon’! Some of list will include only one of these idioms not both.

So if you cram, use only Manhattan or PR. use everything else as a standard usage but not the only use.

More over be smart about how to use idiom list.

Neither … nor-- yes this is idiom so if you see neither…. or it’s wrong. But ‘neither’ can also be used as subject of a sentence.
Not only… but also is idiom and if you see one without another it’s an error.

yes the Manhattan GMAT SC has a good list I ll try to intregrate it as soon as I study SC and then I ll post it on this forum...
