polyglotter
Polyglotter is a term used to describe a person who speaks or actively uses a large number of languages. The word is a neologism formed by adding the English agent suffix -er to polyglot, which itself derives from the Greek polys glōtta, meaning “many tongues.” In usage, polyglotters are often identified by demonstrated fluency across multiple language domains, including speaking, reading, and writing, as well as the ability to switch between languages in conversation. The term is not universally standardized and may be encountered primarily in online language learning communities or in informal writing. Some sources treat polyglotter as a stylistic variant of polyglot, while others use it to emphasize the active practice of multilingualism rather than merely possessing linguistic knowledge.
