The kanji 輪 is a phono-semantic compound (形声文字, けいせいもじ). The left side is a radical called 車, (くるま, "car" or "vehicle"), which provides the meaning component. The right side is 侖 (ろん, "orderly," "to arrange"), providing the phonetic component. Thus, the character originally depicted a wheel, emphasizing its circular shape. Over time, the meaning expanded to encompass other circular or ring-shaped objects.
