One last note about using than

This is a brief and straightforward rule. In sentences where the writer is expressing how something is unlike something else using the word different, the word than is sometimes incorrectly used after the word different. The correct word to use in such a case is from.

• Use from after the word different instead of the word than.

The leaves on this tomato plant look different from the leaves on the others.

The path he chose was different from the one I chose.

In Brief: Use different from, not different than.
