Frame 12
: In its production the dip of the tongue is slightly curved and made to contact the middle of the palate, that is hard palate. This air stream is completely blocked in the middle of the mouth. The soft palate is in raised position so that no air escapes through the nasal cavity. The air is allowed to pass by the sides of the tongue since they are not in contact with sides of the palate. The vocal cords are vibrated in this case. This sound is described as retroflex lateral.
This occurs medially and finally. Medially it occurs as a single consonant in the intervocalic position, as the first member of consonant cluster and in an identical consonant cluster.
Familiarity with 
that is introduced in Frame 9 is to be compared here. This is pronounced by touching alveolar region with the tip of the tongue. But

occurs word initial position whereas
