There are few percieved problems with written english which cannot be resolved by restating.

(Attributed to) Churchill: Ending a sentence with a preposition is something up with which I will not put!"
This, to avoid ending a sentence with "I will not put up with"

He could have easily said: "Ending a sentence with a preposition is somethich which I will not tolerate."
But this would not have emphasised the point nearly so well.
