[Grammar] Playing in/on the playground?

[anikoa]

Playing in/on the playground?

 

[Barb_D]

I'd say "on."

 

[emsr2d2]

I'd say "in", or perhaps "at" but never "on".

 

[anikoa]

How can I decide which one the correct is?

 

[Barb_D]

Different dialects.

Both are correct. I'm American. Ems is British.

You'll get different answers if you ask about "in" the street and "on" the street as well.
