Should "I think in the entire hospital" be considered correct as well?
'I mean, in the entire hospital." DL did not like the comma. Sorry DL, you need it.
Never put a comma between the verb and the rest of the sentence. In a simple sentence at least.
I put "I think of whole hospital" and it was accepted. Such broken English is not correct.
I put "I in the whole hospital" and it was correct. NO that is not correct English.
