The word 维修 is formed by combining two characters, each contributing a core meaning to create a new, composite concept. The first character, 维 (wéi), carries the fundamental idea of "maintaining", "upholding", or "keeping something connected and intact". The second character, 修 (xiū), fundamentally means "to repair", "to fix", or "to restore". When placed together, their meanings merge sequentially and conceptually; the action of 维修 involves both the ongoing act of maintaining (维) something to prevent failure and the specific act of repairing (修) it when it breaks, resulting in the comprehensive sense of "to service", "to maintain and repair".
