As I understand it, in Haida /ʔʷ/ appears in a small number of high-frequency words, but some speakers substitute /ʔ/ instead. Unfortunately, Haida has no known relatives so I don't think the origin of /ʔʷ/ in Haida is known. Masset Haida's epiglottals are pharyngeal in other dialects, though.Frislander wrote:I think I mentioned this before but this is pretty much universal in the Circassian dialect continuum (this is a result of a historical change of uvular ejectives (labialised or not) to glottal stops), I thought it was the only language which had it but thanks for this additional attestation!Zaarin wrote:Some dialects of Haida have /ʔʷ/, which is pretty unusual if I'm not mistaken.
EDIT: Okay, I had a slight mixup. Tlingit, not Haida, has /ʔʷ/. And it's the Hydaburg dialect of Haida with epiglottals; Masset Haida has pharyngeals.
