From Kook Science
Adamic language refers to the language spoken by Adam, the first man, and all of the first generations of humanity, until it was lost after the peoples of Shinar (שִׁנְעָר) attempted to build the Tower of Babel, only to be punished by God who "confounded their language, that they may not understand one another's speech," per Genesis 11.
The Christian tradition of "speaking in tongues," or glossolalia, is sometimes credited as an Adamic or pre-historic language.
Adamic language is referenced in the Book of Moses in the Mormon Pearl of Great Price (chapt. 6, verses 5 & 6):
- "And a book of remembrance was kept, in the which was recorded, in the language of Adam, for it was given unto as many as called upon God to write by the spirit of inspiration;
- And by them their children were taught to read and write, having a language which was pure and undefiled."
