The Origin of Therefor / Therefore

The word “therefore” originates from Middle English therfor, which combined there + for, literally meaning “for that reason”. Over time, “therefore” became the standard spelling in modern English.

“Therefor”, without the extra e, is an archaic form retained in legal language. It appears in older texts, contracts, and statutes, but is uncommon in everyday writing. Its survival in law is due to historical usage and the precision required in legal terminology.
