Thamudic is a name invented by nineteenth-century scholars for large numbers of inscriptions in Ancient North Arabian (ANA) alphabets which have not yet been properly studied. It does not imply that they were carved by members of the ancient tribe of Thamūd. These texts are found over a huge area from southern Syria to Yemen. In 1937, Fred V. Winnett divided those known at the time into five rough categories A, B, C, D, E. In 1951, some 9000 more inscriptions were recorded in south-west Saudi Arabia which have been given the name 'Southern Thamudic'. 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'. The same was done for 'Thamudic E' by Geraldine M.H. King, and this is now known as 'Hismaic'. However, Thamudic B, C, D and Southern Thamudic still await detailed study.
