What does mei mean in latin?

Answer 1

My ,or mine

==============================================

The first answer is theoretically correct, but classical Latin did not usually use the genitive form of ego, the personal pronoun, to mean "my" - this was (99.9 times out of 100) expressed by the possessive pronoun meus, mea, meum. On the very rare occasions when classical writers used mei, it caused some degree of uproar among the Roman readers.
