Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels. They often become automatically fronted, that is partly or completely palatal before a following front vowel, and retracted, that is partly or completely uvular before back vowels.
Palatalised velars (like English /k/ in keen or cube) are sometimes referred to as palatovelars.[by whom?] Many languages also have labialized velars, such as [kʷ], in which the articulation is accompanied by rounding of the lips. There are also labial-velar consonants, which are doubly articulated at the velum and at the lips, such as [k͡p]. This distinction disappears with the approximant [w] since labialization involves adding of a labial approximant articulation to a sound, and this ambiguous situation is often called labiovelar.
A velar trill or tap is not possible: see the shaded boxes on the table of pulmonic consonants. In the velar position, the tongue has an extremely restricted ability to carry out the type of motion associated with trills or taps, and the body of the tongue has no freedom to move quickly enough to produce a velar trill or flap.
The velar consonants identified by the International Phonetic Alphabet are:
|voiceless velar stop||English||skip||[skɪp]||skip|
|voiced velar stop||English||get||[ɡɛt]||get|
|voiceless velar fricative||German||Bauch||[baʊx]||abdomen|
|voiced velar fricative||Greek||γάτα||[ˈɣata]||cat|
|voiceless labio-velar approximant||English||which[note 1]||[ʍɪtʃ]||which|
|velar approximant||Spanish||pagar[note 2]||[paˈɰaɾ]||to pay|
|velar lateral approximant||Mid-Wahgi||aʟaʟe||[aʟaʟe]||dizzy|
|voiced labio-velar approximant||English||witch||[wɪtʃ]||witch|
|kʼ||velar ejective stop||Archi||кIан||[kʼan]||bottom|
|ɠ||voiced velar implosive||Sindhi||g̈əro/ڳرو||[ɠəro]||heavy|
|ʞ||back-released velar click||(paralinguistic)|
Lack of velarsEdit
The velar consonant [k] is the most common consonant in human languages. The only languages recorded to lack velars (and any dorsal consonant at all) may be Xavante, Tahitian, Wutung, Vanimo, Nori, and Waimiri-Atroarí.
Other languages lack simple velars. An areal feature of the Pacific Northwest coast is that historical *k became palatalized in many languages. When such sounds remained stops there were transcribed ⟨kʸ⟩ in Americanist phonetic notation, presumably corresponding to IPA ⟨c⟩, but in others, such as Saanich, Salish, and Chemakum, *k went further and affricated to [tʃ]. Likewise, historical *k’ has become [tʃʼ] and historical *x has become [ʃ]; there was no *g or *ŋ. In the Northwest Caucasian languages, historical *[k] has also become palatalized, becoming /kʲ/ in Ubykh and /tʃ/ in most Circassian varieties. In both regions the languages retain a labiovelar series (e.g. [kʷ], [kʼʷ], [xʷ], [w] in the Pacific Northwest) as well as uvular consonants. In the languages of those families that retain plain velars, both the plain and labialized velars are pre-velar, perhaps to make them more distinct from the uvulars which may be post-velar. Prevelar consonants are susceptible to palatalization. A similar system, contrasting *kʲ with *kʷ and leaving *k marginal at best, is reconstructed for Proto-Indo-European.
Apart from the voiced stop [ɡ], no other velar consonant is particularly common, even the [w] and [ŋ] that occur in English. Of course, there can be no phoneme /ɡ/ in a language that lacks voiced stops, like Mandarin Chinese, but it is sporadically missing elsewhere. Of the languages surveyed in the World Atlas of Language Structures, about 10% of languages that otherwise have /p b t d k/ are missing /ɡ/.
Pirahã has both a [k] and a [ɡ] phonetically. However, the [k] does not behave as other consonants, and the argument has been made that it is phonemically /hi/, leaving Pirahã with only /ɡ/ as an underlyingly velar consonant.
Hawaiian does not distinguish [k] from [t]; ⟨k⟩ tends toward [k] at the beginning of utterances, [t] before [i], and is variable elsewhere, especially in the dialect of Niʻihau and Kauaʻi. Since Hawaiian has no [ŋ], and ⟨w⟩ varies between [w] and [v], it is not clearly meaningful to say that Hawaiian has phonemic velar consonants.
Several Khoisan languages have limited numbers or distributions of pulmonic velar consonants. (Their click consonants are articulated in the uvular or possibly velar region, but that occlusion is part of the airstream mechanism rather than the place of articulation of the consonant.) Khoekhoe, for example, does not allow velars in medial or final position, but in Juǀ'hoan velars are rare even in initial position.
Normal velar consonants are dorso-velar: The dorsum (body) of the tongue rises to contact the velum (soft palate) of the roof of the mouth. In disordered speech there are also velo-dorsal stops, with the opposite articulation: The velum lowers to contact the tongue, which remains static. In the extensions to the IPA for disordered speech, these are transcribed by reversing the IPA letter for a velar consonant, e.g. ⟨k⟩ for a voiceless velodorsal stop.[note 3]
