Re: Xhosa?

    Very quickly, the IPA for clicks are as follows:

O with a dot in the middle=bilabial click (kissing sound)
|=dental click (not use din English)
!=post-alveolar click (ntch, ntch, ntch!  Naughty, naughty!  Also "no" in
Arabic.)
|with two horizontal lines across it=palato-alveolar click (Is it in English?)
|| with the lines closer together=alveolar lateral click (used to spur on
horse)

    I have NO idea how they'd be written in X-SAMPA.  As for Romanization...
Isn't the "x" in Xhosa for a post-alveolar or retroflex click?  One of those.
    If you want to see a full IPA chart with soundfiles to accompnay each
syllable, go to this website:

    You click on each region and then click on the individual sounds.  It's
got all the clicks I listed there.
