Therefor or Therefore – Quick Answer
- Therefore – This is the correct and widely used word when showing cause and effect.
Example: I missed the bus; therefore, I was late for work. - Therefor – This is an archaic or legal term meaning “for that” or “for it.” It is rarely used in modern English except in legal documents.
Example: The payment was made therefor.
✅ Quick Tip: In almost all everyday writing, use therefore.
The Origin of Therefor and Therefore
- Therefore comes from Middle English “therfore”, a combination of “there” + “for,” used to show consequence. Over centuries, it became standardized in general English writing.
- Therefor also originates from the same roots but was historically used in legal and formal contexts, meaning “for that” or “for this purpose.” Its usage has dwindled outside contracts, law, or formal agreements.
In short:
- Therefore → Cause and effect, common English.
- Therefor → For that purpose, legal/archaic.
