Re: It's noisy with the window open/opened and too hot with the window close/closed.
It's a common cause of confusion among learners. The two most frequently used descriptions for doors and windows are "open" and "closed". Learners get confused because "closed" looks like a past participle and they assume that the opposite of "closed" must end
"-ed". However, the two adjectives are simply "open" and "closed".
Of course, the verbs "to open" and "to close" have forms which end "-ed".
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
