However, it also brought some problems during the development. Especially after the mental movements became affective at certain regions, definition of concept in Nahivlearning like all other branches of learningwas point of debate as well. The main reason for this problem is that Nahivists criticize each other on the basis of the criteria proposed by the logicians.In fact, it is seen that all the linguistic and grammarians who wrote a new nahiv book or annotated a written nahiv book, discuss like a logicians on definition of partitions ( Taksim ) after giving the place to partition in the form of name, verb and letter found at introduction of work. Besides, the simplicity of the definitions, not being inclusive, the fact that some of the criteria that are clear or not to be included in the search for an impeccable definition by ordering a number of wordsmake the existing concept-term problem more prominent and they do not provide a better understanding of these concepts.
