List of polyglots

A polyglot is a person who learns and uses six or more languages. A polyglot may also be called a multilingual person; the label "multilingual" is used for communities as well as individual speakers.

Richard Hudson, professor emeritus of linguistics at University College London, coined the term "hyperpolyglot" for a person who can speak twelve or more languages fluently. Other scholars apply the label to speakers of even more languages – twelve, sixteen, or in the most extreme cases even fifty or more.

It is difficult to judge which individuals are polyglots, as there is no uncontroversial definition for what it means to "master" a language, and because it is not always clear where to distinguish a dialect from a language. Being able to communicate in a language does not mean the person has "mastered" a language. There are far fewer who have attained higher levels of multi-linguistic attainment, and there is no basis for testing those levels, or at least those levels of ability have not been noted here. Rosetta Stone is an example of a program that teaches people to "speak" a language, but it does not offer the depth of linguistic knowledge attainable through higher academic education and other means of attaining higher levels of linguistic capability in foreign languages.

This list consists of people who have been noted in news media, historical texts, or academic work as speaking six or more languages fluently. For general discussion of the phenomenon, including discussion of polyglot savants, see polyglotism.
