Nasal clicks areclick consonants pronounced withnasal airflow. All click types (alveolarǃ,dentalǀ,lateralǁ,palatalǂ,retroflex𝼊 andlabialʘ) have nasal variants, and these are attested in four or fivephonations:voiced,voiceless,aspirated, murmured (breathy voiced), and—in the analysis of Miller (2011)—glottalized.[1]
Modallyvoiced nasal clicks are ubiquitous: They are found in every language which has clicks as part of its regular sound inventory. This includesDamin, which has only nasal clicks, andDahalo, which has only plain and glottalized nasal clicks. They are fully nasalized throughout, like the pulmonic nasal[m] and[n]. That is, you pronounce a uvular[ɴ] sound (like Englishng) 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 ⟨ᵑǃ⟩; in Khoekhoe, they are written⟨ǃn ǁn ǀn ǂn⟩, in Juǀʼhõa as⟨nǃ nǁ nǀ nǂ⟩, and in Zulu, Xhosa, Sandawe, and Naro as⟨nc nx nq ntc (nç)⟩.
Aspirated nasal clicks, often described asvoiceless nasal with delayed aspiration, are widespread in southern Africa, being found in all languages of theKhoe,Tuu, andKx'a language families, though they are unattested elsewhere. They are typically transcribed something like ⟨ᵑ̊ǃʰ⟩; in Khoekhoe, they are written⟨ǃh ǁh ǀh ǂh⟩, and in Juǀʼhõa as⟨ǃʼh ǁʼh ǀʼh ǂʼh⟩. 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 (thevoice onset time) may include weak breathy-voiced aspiration at the end. However, when embedded in a phrase after a vowel they tend to be partially voiced; the preceding vowel will [[also benasalized or the click prenasalized]], for a realization of[!˭ʰ] vs[ŋ͡nǃ̬ʱ𐞁]. They have atone-depressor effect, so that a level tone on the following vowel will be realized as rising.
The description above is typical, characteristic of languages such asKhoekhoe andGǀui. However, aspirated nasal clicks have a more extreme pronunciation inTaa, 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).[2]
Breathy-voiced (murmured) nasal clicks are less common. They are known from!Kung languages such asJuǀʼhoansi, fromTaa, and from the Bantu languagesXhosa andZulu. They are pronounced like modally voiced nasal clicks, but in addition are followed by a period ofmurmured 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 ⟨ᵑǃʰ⟩ or ⟨ᵑǃʱ⟩; in Juǀʼhõa, they are written⟨nǃh nǁh nǀh nǂh⟩, and in Zulu and Xhosa, as⟨ngc ngx ngq⟩. In IPA, they could be either ⟨ᵑǁʱ⟩ or ⟨ᵑ̈ǁ⟩
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.[3]
Glottalized nasal clicks are extremely common, but are covered in another article:Glottalized clicks.
There are alsopreglottalized nasal clicks. These are pronounced like modally voiced nasal clicks, but the click release is preceded by a short period of nasalization that has aglottal-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, andǂHoan. (Taa also has preglottalized non-click nasals, though Ekoka apparently does not.)
