That's different than

My email grammarian checked me today. I wrote "different than." It's OK, but not the best.

"The phrases "different from" and "different than" are often used interchangeably, but there are some distinctions:

"Different from" is the more widely accepted usage, especially in British English, and is preferred in formal writing.

 
"Different than" is commonly used in American English, particularly when introducing clauses, though it is less formal.

 
In general, "different from" is considered the standard form, while "different than" may sound awkward to some.

 
In summary, while both phrases can be used, "different from" is the safer choice in most contexts."

My bad.
