What does shadow mean?
Shadow is a familiar English word whose basic meaning is a dark area formed when an object blocks light. Its edges may be sharp or diffuse, and the shape or length of a shadow can reveal the position of its source, the object casting it, and the direction of the light. The word also has several figurative meanings. A person described as someone’s shadow closely resembles or accompanies that person. A shadow of something may mean a faint trace, suggestion, or limited version of it, as in “a shadow of a doubt.” As a verb, to shadow someone means to follow them closely, sometimes with the implication of surveillance; to shadow a plan or proposal means to oppose or undermine it. The word is useful both for describing ordinary physical effects and for expressing ideas involving obscurity, influence, resemblance, secrecy, and control. Its related adjective, shadowy, additionally means indistinct, poorly defined, or disreputable.

Where does shadow come from?
Shadow descends from Old English sceadu, also recorded as sceadwe, meaning “shade, darkness, or shadow.” The word belonged to a Germanic family that includes German Schatten and Dutch schaduw, while the related English word shade shares the same Old English origin. The modern form developed during the Middle English period, with its spelling and pronunciation gradually becoming established in their present forms.
