Where do you think, we are in?
What’s wrong with this sentence? My editor says the following comment.
Review this sentence for preposition use, particularly at the end of sentences The preposition, “in”, is at the end of a sentence. Consider re-wording your sentence so the preposition is not at the end. In informal cases, we often end a sentence with a preposition. When writing formally, ending a sentence with a preposition should be avoided. Prepositions are words like on, in, to, with, from, about and through.
Forget what your grammar checker says, having a preposition at the end of the sentence isn’t a problem in general. The problem is that, in this case, the sentence just doesn’t make sense as written. Based on your comments describing what you would like to say, the sentence you want to write is:
“Where do you think we are?”
Which has the meaning of “In what place do you think we are currently located?”, except it’s more standard spoken English.
