“The Arabic language across the ages” provides a collection of linguistic and philological studies that investigate diachronically and chronologically different aspects of the Arabic language and its dialects. It presents studies on Arabic dialectology (e.g., Arabic North-African dialects), morphology (e.g., The Arabic plural), lexicology and lexicography (e.g., culinary lexicon), phonetics and phonology (e.g., vocalization), syntax (e.g., the function of the particle bi-), sociolinguistics (e.g. A lexical atlas of the Arab world), and history (e.g., dialects of Arabic before and after Classical Arabic).
