This paper was mainly concerned with analyzing the processes of active participle formation in Modern Standard Arabic (MSA). It also aimed to examine the Rural Palestinian Dialect (RPD) in order to reveal the derivation of the active participle in this dialect and to describe any patterns that might vary from MSA. The study was based on the traditional notions of root and pattern which characterize Arabic morphology. The data for this study were collected from various sources. These sources are not researchers but they are people originated from Palestine. Then the data were analyzed in terms of morphology.
