Question

Whats the error? PLEASE DO NOT LEAVE YOUR CLOTHES IN THE LOCKER ROOM OVER NIGHT

Answer 1

Please do not leave your clothes in the locker room over night

Over night, when referring to the duration of a night, is one word. If we were to keep the spacing in between the words, then we would be talking about the locker room being over the night, which isn't possible XD

Thank you for your wuestion! I hope this helped! Have an amazing day! :D

Answer 2

"Over night" should be all one word, "overnight", and there is no punctuation, or proper capitalization, since the sentence is all in caps.
Hope this helps!
