The Chinese word "机器" (jīqì), meaning "machine", is formed through the semantic combination of two characters: "机", which originally denotes a mechanism, pivot, or contrivance, and "器", which signifies a tool, utensil, or instrument. Together, they create a compound where "机" provides the sense of mechanical or automated function, while "器" contributes the idea of a purposeful implement, thus yielding the integrated concept of a "mechanical tool" or device that performs work. This formation exemplifies how Chinese compounds often merge meaningful components to convey a new, unified idea.
