'shadow-created' originates from the combination of 'shadow' and 'create', where 'shadow' refers to a dark area or shape produced by a body coming between rays of light and a surface, and 'create' means to bring something into existence.

'Shadow' comes from Old English 'sceadu', and 'create' comes from Latin 'creare'. The combination of these words into 'shadow-created' is a modern English formation.

Initially, 'shadow' referred to a dark shape, and 'create' meant to bring into existence. Together, they now describe something formed by shadows.
