Rule 1: The throat letters
Six letters come from the throat: ء هـ from the deepest part, ع ح from the middle, غ خ from the top near the uvula. English has only h in this region, so these need the most practice. ح is a strong, breathy h produced by squeezing the middle of the throat; ع is the same squeeze with the voice on. خ is the scraping sound of Scottish loch; غ is the same place with the voice on, like a French r. The throat letters matter later because nūn sākina is pronounced clearly (iẓhār) before them.
