Also, Claire, you might be interested in this usage note from the Oxford Dictinary:
The general rule in British English is that, in restrictive relative clauses, where the relative clause serves to define or restrict the reference to the particular one described, which can replace that.
I think it's time you brushed up on your grammar, Claire!
Mr. Matthews:
Your emotional outbursts cloud your judgment as to what I was contributing to this discussion. For one thing, your logic that because an American President (or, to cover all basis as I look at the logic you employ, "Americans") says something, proves….PROVES your point, needs to be challenged.
Dictionaries now take into account that people, such as yourself (and those less interested in the beauty of the English language sculptured over the centuries) are of the opinion that 'anything goes' and don't discriminate.
I Do see the importance of the difference and say so. You seem to feel a need to attack me for saying so!
