Hi graceren,Hi, everyone!
I think that a "playroom" should be in a house for kids not in a kindergarten. Is it right?
For a discussion of the words used in other varieties of English for what is called a 'kindergarten' in AE see:PS I would recommend you not to use kindergarten (at least in the UK). It sounds terribly old-fashioned to me, although American speakers may use it.
I think kindergarten is considered a playroom.I just wonder whether there would be a playroom in a kindergarten. And now I think it is unusual in America, right?
