整備
せいび · seibi · JLPT N2 · noun
care
🔧 整 (put in order) + 備 (prepare) = keep things in order and ready = maintenance
Used for car maintenance and aircraft overhaul alike. 整 means arrange and 備 means equip, so 整備 means returning something to working order.
整 — 束 bundle + 攵 tap/strike + 正 correct/upright
A compound character combining 敕 (to arrange, with 束 'bundle' and 攵 'strike/action') over 正 ('upright, correct'). The image is of striking a bundle into proper alignment, giving the meaning 'to put in order, arrange neatly.' From this came senses of 'whole, complete, tidy.'
