Abjadi order

The Abjadi order of the Arabic alphabet has two slightly different variants. The Abjadi order is not a simple historical continuation of the earlier north Semitic alphabetic order, since it has a position corresponding to the Aramaic letter samekh/semkat ס, yet no letter of the Arabic alphabet historically derives from that letter. Loss of samekh was compensated for by the split of shin ש into two independent Arabic letters, ش (shīn) and ﺱ (sīn) which moved up to take the place of samekh.
The most common Abjadi sequence is:
أ ب ج د ﻫ و ز ح ط ي ك ل م ن س ع ف ص ق ر ش ت ث خ ذ ض ظ غ
ʼ b ğ d h w z ḥ ṭ y k l m n s ʻ f ṣ q r š t ṯ ḫ ḏ ḍ ẓ ġ
This is commonly vocalized as follows:
ʼabǧad hawwaz ḥuṭṭī kalaman saʻfaṣ qarašat ṯaḫaḏ ḍaẓaġ.
Another vocalization is:
ʼabuğadin hawazin ḥuṭiya kalman saʻfaṣ qurišat ṯaḫuḏ ḍaẓuġ
Another Abjadi sequence (probably older, now mainly confined to the Maghreb), is:
أ ب ج د ﻫ و ز ح ط ي ك ل م ن ص ع ف ض ق ر س ت ث خ ذ ظ غ ش
ʼ b ğ d h w z ḥ ṭ y k l m n ṣ ʻ f ḍ q r s t ṯ ḫ ḏ ẓ ġ š
which can be vocalized as:
ʼabuğadin hawazin ḥuṭiya kalman ṣaʻfaḍ qurisat ṯaḫuḏ ẓaġuš
Modern dictionaries and other reference books do not use the abjad order to sort alphabetically; instead, the newer hijāʼī (هجائي) order (with letters partially grouped together by similarity of shape) is used:
أ ب ت ث ج ح خ د ذ ر زس ش ص ض ط ظ ع غ ف ق ك ل م ن ه و ي
ʼ b t ṯ ǧ ḥ ḫ d ḏ r z s š ṣ ḍ ṭ ẓ ʻ ġ f q k l m n h w y
