퇴근(n) : ending the day's work and going home. 下班. 퇴근하다 is the common verb. 길(n) : 1) road, way, path, passage, 2) suffix meaning "as a way or part of something". 길 can make new compound words by attaching to other nouns. - 퇴근길 : the commute from work to one's home. 퇴근길에 = on the way home. - 출근길 : the commute from home to work. 출근길에 = on the way to work. - 손길 : 손(hand) + 길 = movement or touch of the hand. - 발길 : 발(foot) + 길 = movement or direction of the feet. - 눈길 : 1) 눈(eye) + 길 = gaze or sight line of the eyes. 2) 눈(snow) + 길 = snow-covered road. - 밤길 : 밤(night) + 길 = nightly road, nightly journey, going somewhere at night.
