The Impact of Diglossia on Inflectional Morphological Constructions and Their Relation to Literacy Skills: A Longitudinal Study.

This study highlights the impact of diglossia-specific morphological differences (prevalence of the use of the morphological construction in Arabic in SpA vs. StA) on reading and literacy measures, especially the contribution of morphological awareness in SpA, which may provide a stronger basis for StA reading skills. The implications of these results are discussed, especially regarding exposing children to the morphological representations of both the SpA and StA forms to promote reading and literacy in Arabic.
