The kanji 週 is a phono-semantic compound. The left side is "辶" (しんにょう - shinnyou), a radical related to movement or going. The right side is "周" (しゅう - shuu), which means "circle" or "circumference" and also gives the sound. Therefore, it combines an element of time, movement, and a circular or cyclical nature, reflecting how weeks cycle. The "周" suggests a cycle, which complements the idea of a week as a repeating period.
