though

Etymology

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thagh, from Old English þēah (“though, although, even if, that, however, nevertheless, yet, still; whether”), later superseded in many dialects by Middle English though, thogh, from Old Norse *þóh (later þó); both from Proto-Germanic *þauh (“though”), from Proto-Indo-European *to-, suffixed with Proto-Germanic *-hw < Proto-Indo-European *-kʷe (“and”). 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.
