An Idiom or idiomatic expression is a form of expression of words in their peculiar form as prevalent in a language.The words used have different meanings to their literal meanings. An idiom has its metaphorical rather than literal meaning. The use of words in an idiom is fixed.These idioms undergo changes with the passage of time.
The usage of idioms enhance the beauty of a language and give richness to it. Idioms usually comprise of a few words but these words have their own meanings different from their literal meanings. Just as the meaning of put is different from when some words are added to it as --Put up, Put out , Put off or To put up for a rainy day etc. These words are to be used as they are and these cannot be changed at all. The grammatical use of these words is fixed.For example He has his own axe to grind cannot be changed to ground his axe or some other form. Idioms have their meanings in metaphorical sense rather than literal one.
Idioms add richness to a language but their correct and appropriate use is necessary. Here is a list of idioms with their meanings and usage though it is illustrative and not exhaustive.
