Though the first pronoun ''I''  is a singular , we use have with I . Why is it so? Why can't we use has with all the singular pronouns.... like  she has, he has, it has, etc. Why is it necessary to use have with I? why can't we use has with I? some says that it sounds strange. It sounds strange because experts consider it as an error... I wish if I could get a convincing answer..

ok...this is lyk gettin me real confused..but anyway....u use i have and she has.....so for singular pronouns u mostly use the plural possesives....like u say he has...but has is plural....i is and exception...u use i have not i has.....and for the plural pronouns u use the plural possesives....like they have...wehave an' alll....hope that solved the prob....thumbs up if it did.....,pleeeez
