Tutoring English, grammar is Queen. The tutor talks about “different from” and “different than.”
I recall my mother’s always correcting the combination different than, saying it should instead be different from. Yet, I’ve seen different than in an English textbook. Who’s right?
Both, it turns out: different from is best for formal writing, but different than is still okay in everyday writing, especially in the American context.
Believe it or not, the Brits have their own combination which I seldom hear: different to.
