I know apna/apni means mine/own and mera/meri means my but those meaning mean the same to me. Lets use an example sentence. I want to say I was playing with my cat. I know this sentence is wrong but this is my attempt. Main ne mera billko khelna kiya ta. I is the subject and we add the ne part because play is a transitive verb(I think) and mera billoko refers to my cat. The ko signifies that cat is the indirect object. I really didnt know how to conjugate the verb play so I used its original form khelna and just added the kiya ta to say I was playing. However I was also thinking could I also make this sentence with apna. I was thinking Main ne apna billko kelna kiya ta(I just switched mera with apna) but I know this sounds wrong. I think we don't use ne if we're using apna. Could someone try explaining whether or not each of my sentences are right with the reason and then creating two new sentences using mera and apna respectively?
