The word 收买 is formed by combining two characters, each contributing a layer of action to create a unified, metaphorical meaning. 收 (shōu) carries the sense of "to receive" or "to gather in", while 买 (mǎi) means "to buy". Conceptually, they merge not as a simple sum but as a sequential process: the act of buying (买) is directed inward, with the intent to acquire and bring under one's control (收). This fusion transforms the concrete idea of a commercial purchase into the abstract concept of illicitly acquiring something intangible, like loyalty or influence, effectively "purchasing to take possession of".
