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 stop, which means it is produced by obstructing airflow in the vocal tract. Since 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 sub-apical - 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).
- Its phonation is voiced, which means the vocal cords vibrate during the articulation.
- It is a nasal consonant, which means air is allowed to escape through the nose, either exclusively (nasal stops) or in addition to through the mouth.
- Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
