週
しゅう · shuu · JLPT N3 · noun
week
📅 週 = 周 (go around) + 辶 (movement): the days make one full lap
周 means a circuit or all the way around, and 辶 is the radical for moving along a path. A week is one complete lap through the seven days. Sound hook: shuu is like shoe, and a shoe walks one lap each week.
