Types of nasal clicks
Modally voiced nasal clicks are ubiquitous: They are found in every language which has clicks as part of its regular sound inventory. This includes
Damin, which has only nasal clicks, and
Dahalo, which has only plain and glottalized nasal clicks. They are fully nasalized throughout, like the pulmonic nasal and . That is, you pronounce a uvular sound (like English ''ng'') with the back of your tongue, and make the click sound in the middle of it using the front of your tongue. They are typically transcribed something like ; in Khoekhoe, they are written , in Juǀʼhõa as , and in Zulu, Xhosa, Sandawe, and Naro as .
s, often described as ''voiceless nasal with delayed aspiration'', are widespread in southern Africa, being found in all languages of the
Khoe,
Tuu, and
Kx'a language families, though they are unattested elsewhere. They are typically transcribed something like ; in Khoekhoe, they are written , and in Juǀʼhõa as . Initially and in citation form, words with these consonants are pronounced with voiceless nasal airflow throughout the production of the click and in some languages for an extended time afterward; this period of up to 150 ms (the

In phonetics, voice onset time (VOT) is a feature of the production of stop consonants. It is defined as the length of time that passes between the release of a stop consonant and the onset of voicing, the vibration of the vocal folds, or, accor ...

The description above is typical, characteristic of languages such as
Khoekhoe and GÇ€ui language">GÇ€ui. However, aspirated nasal clicks have a more extreme pronunciation in Taa language">Taa, where they need to maintain a distinction from both the plain voiceless and breathy-voiced nasal clicks. In this language they are not voiced after vowel sounds except in rapid speech, and in addition do not have nasal airflow; Trail reports that they instead have active ingressive pulmonic airflow (that is, air is breathed in the nose rather than being vented out).
Breathy-voiced (murmured) nasal clicks are less common. They are known from !Kung languages such as Juǀʼhoansi, from
Taa, and from the Bantu languages Xhosa language, Xhosa and Zulu language, Zulu. They are pronounced like modally voiced nasal clicks, but in addition are followed by a period of
murmured phonation, and like other breathy-voiced consonants, may have a depressor effect on tone (in Zulu and Xhosa, for example). They are typically transcribed something like or ; in Juǀʼhõa, they are written , and in Zulu and Xhosa, as . In IPA, they could be either or
Voiceless nasal clicks distinct from voiceless aspirated clicks are only attested from one language,
Taa, which changes the voicing of the initial consonant to distinguish singular and plural nouns. In this language, both voiced and voiceless nasal clicks (but not the aspirated and breathy-voiced nasal clicks) nasalize the following vowel; they are largely distinguished by voiceless vs. murmured nasalization leading up to the click release, and the voicelessness occurs even after vowels.

Glottalized nasal clicks are extremely common, but are covered in another article:
Glottalized clicks.
There are also preglottalized nasal clicks. These are pronounced like modally voiced nasal clicks, but the click release is preceded by a short period of nasalization that has a
glottal-stop onset. They are considered unitary consonants, and not sequences of glottal stop plus nasal click. They are only reported from a few languages:
Taa,
Ekoka !Kung, and
ǂHoan. (Taa also has preglottalized non-click nasals, though Ekoka apparently does not.)
