Nasal clicks are click consonants pronounced with nasal airflow. All click types (bilabial ʘ, dental ǀ, alveolar ǃ, lateral ǁ, palatal ǂ, and retroflex 𝼊) have nasal variants, and these are attested in four or five phonations: voiced, voiceless, aspirated, murmured (breathy voiced), and—in the analysis of Miller (2011)—glottalized.

Nasal click in the context of Occlusive
In phonetics, an occlusive, sometimes known as a stop, is a consonant sound produced by occluding (i.e. blocking) airflow in the vocal tract, but not necessarily in the nasal tract. The duration of the block is the occlusion of the consonant. An occlusive may refer to one or more of the following, depending on the author:
- Stops, or more precisely, oral stops—also known as plosives—are oral occlusives, where the occlusion of the vocal tract stops all airflow—oral and nasal.
- Nasals, also known as nasal stops, are nasal occlusives, where occlusion of the vocal tract shifts the airflow to the nasal tract.
- Affricates such as English /tʃ/, /dʒ/ are partial occlusives. Typically stops and affricates are contrasted, but affricates are also described as stops with fricative release, contrasting with simple stops (= plosives).
- Implosives, in which the airstream differs from typical stops and affricates (no examples in English).
- Ejectives, with yet another airstream (no examples in English).
- Click consonants, such as the exclamation tsk! tsk! made when expressing reproach (often humorously) or pity, are double occlusives with yet a fourth airstream mechanism. They may be oral occlusives, nasals, affricates, or ejective.
Oral occlusive may mean any of the above apart from nasal occlusives, but typically means stop/plosive. Nasal occlusive may be used to distinguish the simple nasal sounds from other nasal consonants.
