Gǀui or Gǀwi (pronounced in English, and also spelled ǀGwi, Dcui, Gcwi, or Cgui) is a Khoe dialect of Botswana with 2,500 speakers (2004 Cook). It is part of the Gǁana dialect cluster, and is closely related to Naro. It has a number of loan words from ǂʼAmkoe. Gǀui, ǂʼAmkoe, and Taa form the core of the Kalahari Basin sprachbund, and share a number of characteristic features, including extremely large consonant inventories. Phonology Gǀui has 89 consonants (with 52 clicks) or 52 consonants (and 20 clicks), depending on analysis. There are ten vowels, and two to six tones, again depending on analysis. Clicks Gǀui has 24 simple click consonants, plus complex clicks variously analyzed as consonant clusters or airstream contours. As with many of the Tshu–Khwe languages, clicks have lost some of their importance under the influence of neighboring Bantu languages. Many words which previously began with clicks (as shown by cognates in related languages) have lost them over the past few centuries in Gǀui. Nonetheless, Gǀui has the largest known inventory of clicks of any Khoe language. Gǀui has been described with a contrast between velar and uvular clicks. However, all Gǀui clicks are uvular (or pharyngeal); the 'uvular' part of the latter is part of an airstream contour, a transition from a click to a non-click release: effectively, the click transitions into a non-click consonant. (See Nǁng language for a similar situation in another language.) Nakagawa proposes that the contour and glottalized clicks are not single sounds, but sequences of a click and a uvular or glottal consonant, though Miller (2011) notes that such an analysis creates problems when extended to other languages with clicks. Altogether there are thirteen such series, or "accompaniments", and all 52 possible combinations are found. Except for the lack of bilabial clicks, the inventory is nearly identical to that of some speakers of ǂʼAmkoe, which is in intense contact with Gǀui and may have borrowed some of its clicks from Gǀui, and lost others not found in Gǀui. Miller (2011), in a comparative study with other languages, interprets Nakagawa's description as follows. (Nakagawa's and are analyzed as and , respectively.) The voiced contour ('uvular') clicks tend to be prenasalized, . As in the majority of languages with clicks, the glottalized nasal series are pronounced with a glottal release in initial position, and prenasalized after a vowel.
