[5] Many scholars believed that the various ANA alphabets were derived from the ASA script, mainly because the latter was employed by a major civilization and exhibited more angular features.
[9] Dadanitic was the alphabet used by the inhabitants of the ancient oasis of Dadan (Biblical Dedān, modern Al-`Ula in north-west Saudi Arabia), probably some time during the second half of the first millennium BC.
It lies in northern Saudi Arabia at the south-eastern end of the Wādī Sirḥān which leads up to the oasis of Azraq in north-eastern Jordan.
According to the Assyrian annals Dūma was the seat of successive queens of the Arabs, some of whom were also priestesses, in the eighth and seventh centuries BC.
[10] Hasaitic is the name given to the inscriptions — mostly gravestones — which have been found in the huge oasis of Al-Hasa in north-eastern Saudi Arabia at sites like Thāj and Qatīf, with a few from more distant locations.
[10] Safaitic is the name given to the alphabet and variety of Old Arabic used by tens of thousands of ancient nomads in the deserts of what are now southern Syria, north-eastern Jordan, and northern Saudi Arabia.
About the same time an Assyrian official west of the Euphrates reported that he had ambushed a caravan of the people of Taymāʾ and Sabaʾ (an ancient South Arabian kingdom, Biblical Sheba) because it had tried to avoid paying tolls.
Further study by Winnett showed that the texts he had called 'Thamudic A' represent a clearly defined script and language and he therefore removed them from the Thamudic 'pending file' and gave them the name 'Taymanite', which was later changed to 'Taymanitic'.
