Development of Verb Inflectional Complexity in Palestinian Arabic

We propose three principles for the development of PA verb inflection: (a) Adjacency: Affixes adjacent to the base are acquired first. (b) R-salience: Suffixes are acquired earlier than prefixes. (c) Obligatoriness: Obligatory morphemes precede optional ones. These principles predict the girl's morphological development and reflect sensitivity to PA's richly inflecting typology. This study highlights the need for detailed descriptive research that is essential for understanding language acquisition processes and informing assessment tools, intervention programs, and educational curricula for PA-speaking children.
