There foreとは意味・読み方・使い方

出典:『Wiktionary』 (2026/05/10 21:30 UTC 版)

語源

From 中期英語 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.
