noun
one's course; one's path; one's road
Refers to the path or course one takes in life or travel; somewhat literary and not an everyday word. Often used in figurative or formal contexts.
人生の行路は時に険しい。
The path of life is sometimes steep.
彼は自分の行路を迷わず進んだ。
He proceeded on his course without hesitation.
道 is the common word for 'road' or 'path' in both literal and figurative senses. 行路 is more literary and emphasizes the course one follows, often in life.
進路 means 'course' or 'route' with a forward-moving nuance, often used for career paths or navigation. 行路 is broader and can refer to the entire journey or life path.
Compound of 行 (going, journey) and 路 (path, road). The exact historical derivation is uncertain, but the kanji combination naturally conveys 'the path one travels'.
