Therefor or Therefore – What’s the Difference?

Therefore is a popular word. If you have ever taken a course in formal logic, you will know that the word therefore is a staple of both deductive and inductive reasoning. Therefore signals that the argument has laid out all its premises and is now ready to conclude.

Therefor, however, is much less popular than therefore. It rarely appears outside of legal or financial documents. Even some experienced writers think that it is simply a misspelling of therefore.

Therefor, in fact, is its own separate word with its own meaning and usage cases.
