Revision and classification of different kinds of present participles

In this research, we have had an exact categorization for different kinds of derivational , compound and derivational-compound present participles in the frame of typological prototypes which is a universal approach towards the parts of speech. In this theory, prototypical and with no morphemes adjectives belong to the semantic class of ‘property’ and to ‘modification’ in terms of propositional act constructions. These prototypical adjectives should be simple and without any morphemes on the basis of structural coding of typological prototypes theory. And the adjectives which are not simple and have morphemes, are considered as marked and non- prototypical adjectives. present participles do not act similarly and are not uniform on the basis of behavioral potential. So, they are not in the same level. They are different in terms of their adjectival, nominal functions. By studying present participles in this research, it is shown that they follow the both criterion of typological prototype, and on the basis of these criterion they are non-prototypical adjectives in Persian. In other words, they are unmarked category in terms of both structural coding and behavioral potential. Finally, their position is specified on the semantic map and their behavioral potentials are shown through diagrams
