Archaism's purpose in history is to suggest a better, but perhaps fictional, ancient golden period. It may also be utilized to produce irony and comedy. The sound patterns of archaic words, on the other hand, are useful when it comes to assonance, alliteration, and rhyme scheme. Poets often enjoy this aspect of language use alone or with their readers/listeners. Archaic language is language that is old or new, traditional or modern, that has not been updated to reflect changes in society and technology. It can be found in many different languages at all levels from simple everyday phrases to complex literary works. Often poets will choose archaic words or phrases because they sound beautiful or fit within the context of the poem better. This is called "archaicization". Some examples include: "mandrake root", "spider's web", and "enchantment". These words are not actually older than others but they do offer viewers a glimpse into the past while still being appealing today. Archaic words can be found throughout literature dating back as far as 400 B.C. but have become more common in modern times. Sometimes poets use archaic words to create an atmosphere of mystery or fantasy. This is called "fusion".
