In English, you won't always be thrown in the penalty box for ending a sentence with "is." However, to craft tighter sentences, avoid it. Let's see why.
George W. Bush is who the current president is.This might sit well in casual conversation, but represents sloppy writing. "George W. Bush is the current president" works just fine.
Before considering a solution, we must first understand exactly what the origin of the problem is.Ending with "is" often creates an awkward, deflated conclusion to a sentence--and an inflated word count. Compare:
Before considering a solution, we must first understand the exact origin of the problem.Better, with the punch landing on "problem," but still trim-worthy:
Before considering a solution, we must understand the origin of the problem.Bye-bye, "first." Bye-bye, "exact."
Literary genius? Not yet--but closer to a slim, rhythmic sentence that can dance. After all, that's what good writing is. I mean, that's good writing.
