Please Help me.
Can anyone tell me the use of -/;/:/'/" in the sentences, also tell me what is the difference between "schoolroom" and "school room".
Re: Please Help me.
For the use of punctuation, see here: OWL: Handouts: Grammar, Punctuation, and Spelling
There is no difference in meaning between school room and schoolroom. Either can be used, though the second is becoming more common.
