We have now finished an important part of grammar i.e. Tenses
Let us move towards different forms of pronouns used for preposition

In English “with” preposition is used as “with me”, “with him” etc.
“with” in Marathi is बरोबर (barobar)
“with me” –>माझ्या बरोबर ( mAjhyA barobar )
“with you” –> तुझ्या बरोबर ( tujhyA barobar )

You can observe that the preposition in Marathi comes after the noun. So it is rather a postposition!! Also, note that while using the preposition in English; for “I” we used “Me”; for “He” we used “Him”.
Similarly in Marathi for मी (mI ) we used माझ्या( mAjhyA )
For तू ( tU ) we used तुझ्या ( tujhyA )

These changed forms are called सामान्य रूप (sAmAnya rUp) in Marathi or Oblique case form in English.

Below table list such forms. So by appending the preposition we can create required word :

Note: for “He” and This(male) etc. there are two सामान्य रूप (sAmAnya rUp) are mentioned. Both are grammatically correct. But first form viz. त्याच्या(tyAchyA), ह्याच्या (hyAchyA), etc. are used more frequently than second form viz. त्या(tyA),ह्या(hyA) etc..
The second form is generally used in formal Marathi writing.

The pronoun for “self” is स्वतः (svatH) and its सामान्य रूप (sAmAnya rUp) is same i.e. स्वतः (svatH)
