Definition: A polyglot is someone who knows and is able to use several languages. The term can also refer to a book or text that contains multiple languages, or to multilingualism as a general concept.
Etymology and Origin: The word “polyglot” is derived from the Greek words “πολύς” (polys), meaning “many,” and “γλῶττα” (glōtta) or “γλῶσσα” (glōssa), meaning “tongue” or “language.” It entered English in the early 17th century, initially referring to texts in multiple languages before coming to describe multilingual individuals.
