First published in 1988. Arabic linguistics is developing into an increasingly interesting and important subject within the broad field of modern linguistic studies. The scope of this discipline is wide and varied, covering diverse areas such as Arabic phonetics, phonology and grammar, Arabic psycholinguistics, Arabic dialectology, Arabic lexicography and lexicology, Arabic sociolinguistics, the teaching and learning of Arabic as a first, second, or foreign language. The present work by Prochazka is the first general survey of the dialects of Saudi Arabia covering a wide range from north to south recording of linguistic variation in that vast region. It is particularly strong in covering a number of localities in the southwest and it is the first linguistic study of the dialect of the Ruwala bedouin of the northern desert. The work reveals a major division into two areal blocks: (i) the southern Hijaz and Tihamah and (ii) the Najdi and Eastern Arabian dialects.
