indeed, the square is the empty space without the buildings at its borders, and without the small roads you might find in proximity. If there are buildings on the square (inside the square area), they can be part of it.

I can understand that there is an area around the square to which you may refer with the square name, but I would see this as neighborhood rather than the square itself. It could have the same name, but it is a different feature. It will also not have clear borders, oftentimes, unlike the square, so we agree here.

I’ll leave this up to the locals, it may well be as you write but I have no idea. Around here, you will be able to recognize a square by its name, although there can be some other things that are also called like a square (e.g. shopping malls, subway stations taking the name from a square, shops etc.), so not literally every object with the term square in the name will be actually a square.

I don’t see a contradiction, walking and driving by car are both movements (not saying it’s the same)

I agree those grassy areas are a bit strange, they are a different kind of thing compared to a hard scape, usually they are probably either occurring in a rural setting (villages and hamlets) or are a more modern invention (this could be culturally different). I guess you won’t find them inside the historic centers (inside the (former) city walls) in Europe like in Germany or Italy and many other countries but I’m unsure about the Anglo Saxon world, and they may have been added in modern times (e.g. to structure big roads designed for automobile traffic)
