Book excerpt: This volume features a set of selected peer-reviewed articles, which represent research by some very prominent scholars and some promising researchers in the field. The articles cover a wide range of areas in Arabic linguistics, namely Sociolinguistics, Phonetics, Phonology, Morphology, Syntax, and Language Acquisition. They also feature research on a number of Arabic dialects namely Egyptian Arabic, Emirati Arabic, Jordanian Arabic, Lebanese Arabic, Sudanese Arabic, and Syrian Arabic. Some of the contributions engage prominent issues that relate to current development in the Arabic speaking world. For example Reem Bassiouney’s paper is a significant contribution in that regard. Other contributions, such as the ones by Stuart Davis, Abdel-khalig Ali, Lababidi & Park, Ntelitheos & Idrissi, present innovative studies in Arabic Morphology, Phonetics, Phonology, and Language Acquisition respectively. How Arabic can serve as a testing ground for some theoretical constructs and approaches is exemplified by Peter Hallman, Phil Crone, and Youssef Haddad’s contributions in the area of Syntax and its interface with other fields.
