Q. What’s your current recommendation on ending a sentence with a preposition? Current example: “[Nurses bound the] wounds of the men they were taking care of.”

A. Our current recommendation has been current since 1906: there is no rule against ending a sentence with a preposition. Please see CMOS 5.180: “The traditional caveat of yesteryear against ending sentences or clauses with prepositions is an unnecessary and pedantic restriction. And it is wrong.”
