An archaism is a linguistic term referring to the use of older or obsolete words, expressions, or language structures that have fallen out of common usage in contemporary speech or writing.
Archaic elements may be intentionally employed for stylistic, historical, or literary purposes, providing a sense of antiquity or formality.
The use of archaisms can be found in literature, legal documents, or historical contexts, often serving to evoke a specific time period or to convey a particular tone or mood.
