A gift of the Holy Ghost that allows inspired individuals to speak in, understand, or interpret unfamiliar languages. We believe in the gift of tongues (A of F 1: 7).

They were all filled with the Holy Ghost, and began to speak with other tongues, Acts 2: 4. He that speaks in an unknown tongue speaks not to men, but to God, 1 Cor. 14: 1-5, 27-28. Tongues are for a sign to them that believe not, 1 Cor. 14: 22-28. Then cometh the baptism of fire and of the Holy Ghost; and then can ye speak with the tongue of angels, 2 Ne. 31: 13-14. Amaleki exhorted all men to believe in the gift of speaking with tongues, Omni 1: 25. It is given to some to speak with tongues; and to another the interpretation of tongues, D&C 46: 24-25 (1 Cor. 12: 10; Moro. 10: 8, 15-16). Let the gift of tongues be poured out, D&C 109: 36.
