Art Project: Idiomatic Expressions
According to the Merriam Webster online dictionary, an idiom is:
“an expression in the usage of a language that is peculiar to itself either grammatically (as “no, it wasn't me”) or in having a meaning that cannot be derived from the conjoined meanings of its elements (as “ride herd on” for “supervise”).
It is this second definition, in which the sum of the words in context is different from the expected meaning of the phrase, that is relevant to this project.
It is difficult to find authoritative online encyclopedic or dictionary resources that explain the meaning of idiomatic expressions, and also provide information about how they originated. Most of the online resources, while interesting, are not written by authors who provide information about why they can be considered to be experts whose work is reliable. As a result, none of the online sources below is completely authoritative, but at least one of them listed here does include source citations
