配套 (pèi tào) is a verb meaning 'to provide matching or complementary components' or 'to be compatible as a set.' The character 配 (pèi) means 'to match,' 'to pair,' or 'to coordinate,' while 套 (tào) means 'set,' 'suite,' or 'series'—often referring to a group of items designed to work together. Together, they describe the action of supplying or arranging things that belong together logically or functionally.

This word is commonly used in contexts involving infrastructure, products, services, or systems—such as housing developments with配套 facilities (e.g., schools, supermarkets), software with配套 hardware, or curricula with配套 teaching materials. It implies intentionality and design coherence: the components aren’t random but deliberately selected to complement one another. While it can appear as a noun ('a set of配套'), its primary grammatical role is verbal, especially in phrases like 配套建设 (build supporting facilities) or 配套服务 (provide supporting services).
