noun
branch roads; crossroads
Refers to a place where two roads meet or diverge; a rare and somewhat literary term.
旅人は二筋道に立って、どちらへ進むべきか迷った。
The traveler stood at the crossroads, unsure which way to go.
Compound of 二 (ふた, 'two'), 筋 (すじ, 'line' or 'path'), and 道 (みち, 'road'). The exact historical derivation is uncertain, but the spelling is conventionally associated with the meaning of two roads meeting.
