which

Among the most abhorrent of the many ways in which the common mind spits blithe contempt on the English language has been to take the relative pronoun for something like a cheap whore. The trend, apparently ratified by secret ballot, was already underway a decade ago, when I heard a train conductor say (approximately), "Ladies and gentlemen, trains to Chilton, which this is a train to Chilton, will need to stop at Bramford." If the effect on you is one of horror or disgust, then you likely know that he should have said, "...trains to Chilton, and this is a train to Chilton, will need..." or even, "...trains to Chilton, of which this is one , will need..."

The same goes for other relative pronouns, such as who.
