Question

What is the difference between "tum ko, tujh ko, and tujhe"? in hindi or in urdu?

Answer 1

3 words to address others: Aap, tum and tu. Aap is to give respect... when u r talking to seniors, elders or some stranger who can be younger or older  than u. Tum is a bit informal when u r a bit comfortable with another person and tu is to talk to ppl whom u r completely at ease with if they r ur own age or younger than u. You never address ppl older to you with tum or aap (bad manners).

Tumko... tumko milne ke liye aaya tha....(talking to someone u r a bit informal)

Tujh ko milne aaya tha ( some1 completely informal with like a fren or some1 yonger)

tujhe milne aaya tha ( same as tujh ko no diff)

Answer 2

tum ko = {to} you  ( semi-formal address)

tujh ko = {to} you ( informal address )

tujhe = {to} you ( informal )
