On the licensing of glides
This article deals with the behavior of glides in Classical Arabic. I argue that the distribution of glides is determined by their position within a network of licensing relations. When in onset position, a glide must be licensed by a phonetically realized nucleus. If not properly licensed it must delink. The analysis that is proposed in this article has implications for the licensing of onsets in general, the Onset-Nucleus relation, Government Licensing, and the formal status of the hiatus phenomenon. It also addresses the issue of structure preservation, namely the question of whether licensing relations at derived levels must match those established in lexical representations.
