In this research, it has been tried to survey certain Persian sentences and
based on the linguists' ideas the existence of the number phrase in
definition phrase in the Persian Language is demonstrated. Then it has been
attempted to show that the position of the plural morpheme in Persian,
quite similar to the other languages, is the core of the number phrase. Along
with surveying the features of the plural morpheme in Persian the
researchers try to prove that the numbers being more than one do not
accompany the nouns having the plural morpheme in Persian and this
process is due to the specific characteristics of the plural morpheme in
Persian which is also contrary to some other languages.
