Vertimas - Turkų-Anglų - sadece arkadaş olmak istemiştim

Perhaps it should be:
"I only wanted us to be friends"

Does it change the original meaning?

it isnt a big changing, but in original text "I oly wanted to be friend." gives the same meaning.

sadece=only, arkadaş=friend, olmak= to be, istemiştim= I wanted, maybe I had/ have wanted

In English we have to use something before that singular noun "friend".
We can't say "I only wanted to be friend"

Besides the option I gave above, it could be either "I only wanted to be your friend" or "I only wanted to make friends with you".

Ok,how is "I only wanted to be friend with you."?

"to be friends with you" is fine.

with you fazla bu cümle icin

evet fazla ama ingilizce de sadece be friend olarak kullanamazmışız.
