Gciriku, or Dciriku (Also Diriku, Dirico, Manyo or Rumanyo), is a Bantu language spoken by 305,000 people along the Kavango River in Namibia, Botswana and Angola.

[3] It was first known in the west via the Vagciriku, who had migrated from the main Vamanyo area and spoke Rugciriku, a dialect of Rumanyo.

These clicks, of which there are half a dozen (c, gc, ch, and prenasalized nc and nch), are generally all pronounced with a dental articulation, but there is broad variation between speakers.

They are especially common in place names and in words for features of the landscape, reflecting their sources in Khwe and Ju, two so-called Khoisan languages.

Many of the words with clicks in Gciriku, including those in native Bantu vocabulary, are shared with Kwangali, Mbukushu, and Fwe.
