Click sounds in Nguni languages trace back to a very early common ancestor

Cultures · Published 3 October 2026 Swipe more like this →

In short: A linguist examined click consonants across the Nguni branch of Bantu languages, including a rare palatal click no longer heard in any living Nguni language, using the comparative method to trace them back in time. The analysis suggests many of these clicks were already part of Proto-Nguni, the shared ancestor of these languages, rather than borrowed more recently from neighbouring Khoisan-speaking communities.

Clicks entered many southern African Bantu languages through contact with Khoisan speakers, but the timing of that contact has been unclear for the Nguni branch. By reconstructing Proto-Nguni, the author found no new click sounds entered later Nguni languages through additional contact, indicating the clicks were adopted very early rather than gradually accumulated.

This conclusion rests on comparing related languages systematically rather than on direct historical records or archaeological evidence, so the exact circumstances and timing of the original contact remain uncertain.

Why it matters: The sounds a language family uses today can reveal when and how distant communities first came into contact.
