Archaism

In language, an archaism is a word, a sense of a word, or a style of speech or writing that belongs to a historical epoch beyond living memory, but that has survived in a few practical settings or affairs. Lexical archaisms are single archaic words or expressions used regularly in an affair or freely; literary archaism is the survival of archaic language in a traditional literary text such as a nursery rhyme or the deliberate use of a style characteristic of an earlier age—for example, in his 1960 novel The Sot-Weed Factor, John Barth writes in an 18th-century style. Archaic words or expressions may have distinctive emotional connotations—some can be humorous (forsooth), some highly formal, and some solemn.
