🧩 組 (set of parts) + 立てる (stand up) = join the parts, then stand the set up
組 means a set of parts and 立てる means to stand something upright. Assembling joins separate parts into one set, then raises it upright.
立 — person standing on ground (大 over 一)
Pictograph of a person standing with arms outstretched on the ground line below. The original oracle bone form clearly shows a frontal human figure planted on the earth. The core meaning 'to stand' extended to 'establish, set up, erect.'
