It's different FROM

[FlamedToACrisp]

Not different TO or (shudder) different THAN.

If two things are different, they differ FROM each other.

I agree, but I think in the US 'different than' is the norm.

With you @Flame, just like it is ‘she is sitting’ not ‘she is sat’. But language evolved, apparently...

Language is constantly evolving!

'Different than' is standard in the USA.

I am very pedantic but can't get worked up about different to. Jane Austen used it, after all...

All perfectly correct, depending on which variety of English you use.

We tend to still tut quietly at sentences beginning with "But" though. Maybe language will evolve for that as well.

"He was sat" is a different example, as it's simply incorrect grammar.

I am surprised "different than" is the American norm: Robert Heinlein was exceedingly rude about that construction in To Sail Beyond The Sunset, 1987. He called it a barbarism, as far as I remember.
