صيغة (فعلان)‎ و صفا : رأي و تحليل

Abstract EN

This research attempts to answer some questions related to the form (faalan) as a description.

Where the grammarians indicated that it is one of the structures of the adjective that is formed from the source of the verb which Is ( tholathy lazem ), so should I expel its formulation from the source of the the lazem verb? Is its indication of steadfastness and permanence always verified? And if there is a departure from what was approved by the grammarians, in which morphological chapters can this formula be included? In which morphological chapters does the formula (faalan) fall if it is formulated from the source of the transitive ( tholathy lazem ), verb and not the necessary?
