IPA: /ˈfreɪnəm/
KK: /ˈfreɪnəm/
A fold of tissue that connects or restricts the movement of a part of the body, such as the one under the tongue.
The doctor explained that the fraenum under my tongue helps control its movement.
Fraenum is derived from Latin 'fraenum' (meaning bridle or rein). The word refers to a small fold of tissue that connects the tongue to the floor of the mouth, similar to how a bridle connects a horse's mouth to its reins.
Think of a 'bridle' that connects and controls, just like the fraenum connects the tongue to the mouth.
