Glossolalia

Glossolalia
From Wikipedia, the free encyclopedia
Glossolalia is commonly called "speaking in tongues". For other uses of "speaking in tongues", see Speaking in Tongues (disambiguation).

Some uses of 'Glossolalia' (including here) refer to Xenoglossy, speaking in a natural language that was previously unknown to the speaker.
Glossolalia or speaking in tongues is the fluid vocalizing (or, less commonly, the writing) of speech-like syllables, often as part of religious practice. Though some consider these utterances to be meaningless, those that use them consider them to be part of a holy language.
