The special Abjad (أبجدʾabǧad) order of the Arabic alphabet (or two slightly variant orders) was devised by matching an Arabic letter of the fully consonant-dotted 28-letter Arabic alphabet to each of the 22 letters of the Aramaic alphabet (in their old Phoenician alphabetic order) — leaving six remaining Arabic letters at the end. The Abjadi order is not a simple historically-continuous preservation of the earlier north Semitic alphabetic order, since it contains a position corresponding to the Aramaic letter samekh/semkatס, yet no letter of the Arabic alphabet historically derives from ס. Loss of samekh was compensated by the split of shinשinto two independent Arabic letters, ﺱ and ش. Wikipedia does not have an article with this exact name. ...
