 Moreover, even if Nawa'i's thesis were to be accepted as valid, he destroyed his own case by the lavish use, no doubt unknowingly, of non-Turkic words even while ridiculing the Persians for their need to borrow Turkic words.The present writer has not made a word count of Nawa'i's text, but he would estimate conservatively that at least one half the words used by Nawa'i in the essay are Arabic or Persian in origin.To support his claim of the superiority of the Turkic language, Nawa'i also employs the curious argument that most Turks also spoke Persian but only a few Persians ever achieved fluency in Turkic.
