The kanji 機 is a phono-semantic compound (形声文字). The left side is the radical 木 (ki; tree, wood) and the right side is 幾 (ki; a few, small, almost). The original meaning of 機 was related to "loom" or "weaving machine," referring to the wooden frame used to create cloth. Over time, the meaning expanded to encompass the general idea of a machine or device with moving parts, and eventually to more abstract concepts like "opportunity" or "chance" because, like a well-functioning machine, an opportunity must be seized at the right time. The addition of the "tree" radical 木 hints at the original use of wood in the construction of such a device. The right part 幾 provides the phonetic element and also relates to the fine, intricate workings of the weaving process, implying the mechanism.
