hey, D.
to me the context and setting of the audio is important to my mind's eye, when listening.
just wanted to get my 'eyes' right. thanks.
sooo, these new clicks. I'm with you, very odd.
as if, nephie is revealing new aspect of language to you. new phonics.
have you personally ever considered contacting a professional linguist?
these clicks could be telling. it's new evidence or an indication of their language, perhaps.
btw: at some point, nephie drops a large rock that goes 'crack.'
any indication that rock still around the parking area?
as for that 'click.'
some derelict african languages use a system of up to 7 click and cluck variations.
the single click is one of them.
