`::I must apologize profusely.  It is chaf that is the velar fricative (``ch`` in Scottish loch): hhet is the same sound, for non-Arab Jews, and a uvular fricative (much further back in the throat, as in Arabic) for Mizrahim.  I got the two terms muddled up because my browser does not support IPA symbols properly so I couldn't make sense of the table.  Please edit accordingly.    `
