复聲fù — gives the sounda foot returning the way it came — to repeat, go back over
A lined garment, cloth (衤) doubled over for warmth — the original sense is two layers. 复 fù carries the sound and the idea: a foot retracing its path, doing the thing again. From the doubled cloth come all the doublings: 複習 (study again), 複製 (copy), 複雜 (many layers tangled). 复 builds 復、腹、覆.
