Lowth gave us an early suggestion against the sentence-ending preposition: “This is an Idiom which our language is strongly inclined to; it prevails in common conversation, and suits very well with the familiar style in writing; but the placing of the Preposition before the Relative is more graceful, as well as more perspicuous; and agrees much better with the solemn and elevated Style.” Lowth himself wasn’t completely against it (after all, he used it himself in “strongly inclined to”), just passing an aesthetic judgment.
