"Meetings are the time waster there is" vs. "There is a meeting which is the time waster" "Meetings are the biggest time waster there is." It is the sentence I want to understand. I've never seen that 'there is' is put at the end of a sentence. When I saw this sentence, I understood the meaning, but it was weird to me. "Meetings are the biggest time waster there is" vs. "There is a meeting which is the biggest time waster" Do they have the same meaning? And why is 'there is' used in that way? Thank you very much!!
