Should I say “different from,” “different than,” or “different to”?

All three forms are used, but their acceptability depends on region and style.

“Different from” is the safest and most widely accepted choice.

Examples:

• This is different from what I expected.

• Your answer is different from mine.

“Different than” is common in American English, especially before a full clause.

Example:

The result was different than I expected.

“Different to” is common in British English.

Example:

This is different to the previous version.

For formal or international writing, choose “different from.”
