RESUMO
This study investigated the acquisition of word-patterns and roots in the nominal system of the spoken language of Palestinian Arabic (PA) and its distance from Standard Arabic (StA). It described, analyzed, and quantified the nominal system (roots and word-patterns) as reflected in the language corpus of Palestinian-Arab kindergarteners 3 to 6 years old. The results showed that non-linear derived nouns (deverbal nouns) are the most frequently used category (49.5%). Primitive nouns comprise 43.1% of the nouns, whereas linear derived nouns barely exist before children start school (0.3%). Additionally, the results showed that half of the nouns were built from common word-patterns and roots between PA and StA, whereas 30% of the nouns were constructed from different word-patterns with common roots. Although PA and StA have much in common morphologically, there exists a significant degree of divergence.
