Xenoglossy ( or ), also written xenoglossia ( or ), is the putative paranormal phenomenon in which a person is able to speak or write a language he or she could not have acquired by natural means. For example, a person who speaks Swedish fluently, but who is not a native Swedish speaker, has never studied Swedish, never been to a Swedish-speaking country, and never associated with Swedish speakers or had any other source of exposure to the Swedish language, would be said to exhibit xenoglossy.
