"that is something up with which I will not put."

One normative grammarian whose work I enjoy is Robert Lowth, Bishop of London. In the following quotation, note the mildness of his usage suggestion and the sly insertion of a sentence which breaks it. (What, one asks, ought to be written in a "more solemn and elevated style" than a grammar?)

Quote:
The Preposition is often separated from the Relative which it governs, and joined to the Verb at the end of the Sentence, or of some member of it, as, "Horace is an author, whom I am much delighted with." "The world is too well bred to shock authors with a truth, which generally their booksellers are the first that inform them of." 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.
