We report on a new click type found in Mangetti Dune !Xung
(M.D. !Xung) - a forward released denti-alveolar lateral click,
transcribed [ ||| ]. We present acoustic data showing that ||| is
distinct from the "typical" lateral (post-) alveolar ||, and the
central (post-) alveolar !, a conclusion supported by synchronic
and diachronic analyses of Northern Khoisan [1, 2].

We use Adaptive Dispersion  to account for acoustic
differences seen between || in !Xung and Ju|’hoansi, a related
language without the ||| click.
The ! click is distinct from both ||| and || lateral clicks in rise
time till peak intensity [4, 5], burst duration and peak burst
frequency, while ||| and || differ primarily in terms of rise time
and peak intensity.
