Question

رَأَيتَنِي (You saw me)Here the pronoun of the first person is only (-i), but ن is added between the verb and the pronoun (-i) so that the final vowel of the verb may not be affected due to (-i). This nun is called نُون الوِقَايَّةِ (the nun of protection). In رَأَيْتَ if we say (ra'aita-i) or (ra'aiti-i) the Arabic phonetic system requires the omission of the (a) or (i) before the pronoun (-i). So the verb in both cases will become (ra'ait-i) and the difference between the [masc] and [fem] will be lost. That's why ن in inserted.
