Central ǃKung (Central ǃXun), or Central Ju, is a language of the ǃKung dialect cluster, spoken in a small area of northern Namibia: Neitsas, in Grootfontein district, and Gaub, in Tsumeb district. It is frequently reported as Grootfontein ǃXuun, as most research has been done in Grootfontein. An identifying feature of Central ǃKung is a fifth series of clicks that are often retroflex. While Northern (Northwestern) and Southern (Southeastern) ǃKung are not mutually intelligible, it is not yet clear to what extent Central ǃKung is intermediate between them or intelligible with either.

This article includes a list of general references, but it lacks sufficient corresponding inline citations. (May 2019)

Two dialects are identified as being Central ǃKung based on grammatical features:

(C1) Gaub (Tsumeb district, N Namibia)

(C2) Neitsas (Grootfontein district, N Namibia)

In addition, the ǃKung dialects of Tsintsabis, Leeunes and Mangetti (different from Mangetti Dune) have retroflex clicks and so may belong here, though no grammatical information is available to classify them.

In Grootfontein ǃKung words which Doke (1926) and others have described as having retroflex clicks, Vedder (1910/1911) described a second series of lateral clicks in Gaub ǃKung.

Grootfontein ǃKung is unusual in having true retroflex clicks, which are subapical for some speakers and have lateral release, as in the word for 'water', [ᶢ𝼊𐞷ú] (provisionally written g‼ú). There are thus five places of articulation in Grootfontein clicks, /ǃ ǀ ǁ ǂ 𝼊/. These come in eight series, here represented with the retroflex articulation:

Lingual /𝼊 𝼊ʰ ᶢ𝼊 ᵑ𝼊 ᵑ̊𝼊ʰ/, glottalized /ᵑ̊𝼊ˀ/, linguo-pulmonic /𝼊χ/, linguo-glottalic /𝼊͡kxʼ/

Otherwise, the Grootfontein inventory is similar to that of Ekoka ǃKung, except that it lacks the (pre)voiced affricates /dχ, dʒ, dʒʼ, dʃχʼ/.

The Grootfontein ǃKung language has a relatively large phonological inventory:
