Is this your pen? ve This is your pen? arasındaki fark nedir?Sadece örnek cümleler vermekten çekinmeyin.

"Is this your pen?" is something I would ask people if I found a pen on the floor at work or school.

If I had found the pen and kept it for my own use, someone would eventually come up to me and say "Hey, that's mine!", to which I would respond "Oh, this is /your/ pen??"

To me, "Is this your pen?" is a seemingly harmless question, while "This is your pen?" is something I would say if I unknowingly took someone else's pen and they confronted me for doing so.

Hope this helped!
