The lack of a comprehensive etymological dictionary of the best documented and, in many accounts, main Semitic language, i.e., Arabic, is a serious drawback for progress in our knowledge of the background and evolution of lexical studies of the whole Afrasian phylum. Any serious attempt at achieving that goal would require a team of a number of scholars working hard during several years; however, in the meantime, a modest shortcut could be to consecrate some personal efforts in that direction on a single important Arabic dialect, and this is what we are presently trying to bring about, within the project of a linguistic encyclopaedia of Andalusi Arabic. So far, our endeavours have cast some new lights of lexical borrowing not only from well-known cases of Aramean and Persian origins, but also, e.g., from Akkadian and Old Egyptian, as well as a rather detailed account of phonetic changes and lexical composition scarcely detected or never heretofore suspected and having often prevented the recognition of the true etyma of Semitic and non-Semitic stock, of which the present article is, of course, only a résumé and introduction.
