Tamil Script/Sankaran Radhakrishnan
There is one more nasal with three loops shape N(). In its production the
tip of the tongue is curled and made to contact the roof of the mouth. The
soft palate is lowered as in the production of other nasal and the air stream
escapes freely through the nasal cavity. The vocal cords are vibration. This
similar in production with d () except that the air stream is emitted
through the nasal cavity. This may be described as a voiced retroflex nasal.
This never occurs in the word initial position. Medially it occurs as a single
consonant between vowels, as the first member of a consonant cluster, as
the second member of a consonant cluster and in an identical consonant
cluster.
Compare the letter for (na) with the letter for (a) and write them
three times each. Your letters should be similar to the ones at the
extreme right (see Appendix I for hand-movements).
