week
週 centers on the recurring cycle of a week: a seven-day period used for scheduling and timekeeping.
週 combines 辶 (movement) with 周, which likely contributes both sound and the idea of a cycle or circuit, together suggesting a recurring time cycle.
The movement radical 辶 wraps around 周, like a cycle going around and around. Picture a calendar page turning in a loop, marking each week.
For シュウ, imagine a shoe (シュウ) stepping through the days of the week: each step is a new day, and the shoe walks the weekly cycle.
