This is a list of idioms that were recognizable to literate people in the late-19th century, and have become unfamiliar since.
As the article list of idioms in the English language notes, a list of idioms can be useful, since the meaning of an idiom cannot be deduced by knowing the meaning of its constituent words. See that article for a fuller discussion of what an idiom is, and what it is not. In addition, the often-obscure references or shared values that lie behind an idiom will themselves lose applicability over time, although the surviving literature of the period relies on their currency for full understanding.
