Retroflex nasal
The retroflex nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɳ⟩, and the equivalent X-SAMPA symbol is n`. Like all the retroflex consonants, the IPA symbol is formed by adding a rightward-pointing hook extending from the bottom of an en (the letter used for the corresponding alveolar consonant). It is similar to ⟨ɲ⟩, the letter for the palatal nasal, which has a leftward-pointing hook extending from the bottom of the left stem, and to ⟨ŋ⟩, the letter for the velar nasal, which has a leftward-pointing hook extending from the bottom of the right stem.
Features
Features of the retroflex nasal:
Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Because the consonant is also nasal, the blocked airflow is redirected through the nose.
Its place of articulation is retroflex, which prototypically means it is articulated subapical (with the tip of the tongue curled up), but more generally, it means that it is postalveolar without being palatalized. That is, besides the prototypical sub-apical articulation, the tongue contact can be apical (pointed) or laminal (flat).
