About
As a phono-semantic compound, 空 combines the radical 穴 (xué), meaning cave or hole, at the top to indicate its semantic category of a hollow space, with the component 工 (gōng, work) at the bottom to provide its phonetic value. Its core meaning is thus an empty physical space or cavity. This concept extended upward to denote the sky or atmosphere and also developed abstract senses of nothingness, vanity, or lack of substance.
