The value of idioms is that they add life and colour to the language.Is a idiom the same as a collection? I am guessing it is.
AN IDIOM IS: noun 1 a group of words whose meaning cannot be deduced from those of the individual words (e.g. over the moon). 2 a form of expression natural to a language, person, or group. 3 a characteristic mode of expression in music or art.
A "collocation" is: noun 1 the habitual occurrence of a word with another word or words with a frequency greater than chance. 2 a word or group of words that habitually occur together (e.g. heavy drinker).
Also I was wondering about how valid idioms are in proper English. Most seem to be slang, 'A bird in the hand is worth two in the bush' or 'just what the doctor ordered' are many examples of idioms that would not be acceptable when writing English formally.
Idioms are not necessarily slang, though slang is idiomatic. They can be used in formal writing.
However, there are a few that are acceptable English 'abide by a decision' is one - taken from a Idioms dictionary - but is it really a idiom or just a sentence because I could write 'accept the decision' and the meaning would still be the same. I think?
Are idioms more important in American English then UK English? Have about the same value.
Hope someone understands the questions and if they answer thanks for your reply!
