Definition of Tongue tie
Medically reviewed by Min Clinic Staff | Updated: January 2026
Tongue tie: A minor congenital anomaly in which the flap of mucous membrane under the tongue (known as the frenulum) is unusually short and limits somewhat the mobility of the tongue. The name tongue tie reflects the unfounded folk belief that with this condition, a child cannot feed or speak properly because the tongue is 'tied.' The medical term for this condition is ankyloglossia.
