The "1P" and "2P" pronouns (except the formal "2P" pronoun āp) have their own distinctive genitive forms merā, hamārā, terā, & tumhārā unlike the non-personal pronouns whose genitive forms are constructed employing the oblique case pronoun to which the genitive postposition kā is suffixed ("OBL". + "kā). The personal pronouns (except the formal 2P āp) colloquially can also take the genitive oblique case before primary postpositions. So, instead of mujhe or mujhko, the periphrastic construction mere ko is fairly commonly heard as a synonym to mujhe/"'mujhko in colloquial speech.
