Etymology

From Middle English therfore, therfor, tharfore, thorfore; synchronically a univerbation of there (pronominal adverb) + for, literally “for that (reason)”. The spelling has been changed due to a reanalysis as there + fore (literally “forward from that; thence”). See also therefor, ultimately the same formation. Compare Saterland Frisian deerfoar, Dutch daarvoor, German dafür, Danish and Norwegian derfor, Swedish därför.
