Fusion between the tongue and the floor of the mouthComplete lack of the lingual frenumLingual frenum connected at the tongue's tipAbnormally short lingual frenum

True ankyloglossia results from the fusion of the tongue to the floor of the mouth, restricting its movement. Other conditions such as absence of the lingual frenum, frenum attachment at the tongue tip, or a short frenum do not constitute true ankyloglossia.
