Note 8 — ARABIAN NIGHTS' ENTERTAINMENTS
Edward William Lane translation
"Dh is pronounced as th in 'that:' gh represents a guttural sound like that produced in gargling: kh represents a guttural sound like that which is produced in expelling saliva from the throat, and approaching nearer to the sound of ḥ (a very strong aspirate) than to that of k: sh is pronounced as in 'shall:' and th, as in 'thin.'"
