Origin of Though

From Middle English thaugh, thagh, from Old English þēah (“ though, although, even if, that, however, nevertheless, yet, still; whether"), later superseded in many dialects by Middle English though, thogh, from Old Norse *þóh (later þó); both from Proto-Germanic *þauh (“though"), from Proto-Indo-European *to-. Akin to Scots thoch (“though"), Saterland Frisian dach (“though"), West Frisian dôch, dochs (“though"), Dutch doch (“though"), German doch (“though"), Swedish dock (“however, still"), Icelandic þó (“though"). More at that.
