Translation:These are the names of our grandmothers and grandfathers.
Why have to be "the" in front of "names of our..."? Why not without "the"?
Hi Tatka. You can't say These are names of grandmothers. It's correct to say These are names/These are cars/Those are students. But we add "the" at: These are THE names of our grandparents/These are THE names of the cars that I would buy/Those are THE students of my class.
