sounds like 'sway' — to follow/go along with
随 suí means to follow or come right after. The right side 辶 is the 'walk' radical, signaling motion/following. Used in 随后 (suíhòu, afterwards) and 跟随 (gēnsuí, to follow).
随 — 辶 (walk) + 阝 (mound) + 有 phonetic
随 combines the walk radical 辶 with a phonetic component derived from 隋. The original sense is 'to follow along a path,' from the walking radical suggesting movement after someone. Over time it broadened to mean 'follow,' 'accompany,' or 'comply with.'
