I'd appreciate it if anyone could tell me what the British term for 'schoolyard' is? Is 'playground' used for schools too?
Note that this is entirely anecdotal and coincidental. Those words aren't in general use, and I've never heard the word 'redgra' in any other context. But it's worth remembering that some schools have a playground and something else (which'll have a local name). At my elder sister's convent, one of the rules was 'No running in the cloisters' - so I doubt whether much playing happened there.
'The cloisters' was the term used in the local girls school for what we boys called 'the bogs' - the lavatories.
