n. [ OE. shade, shadewe, schadewe, AS. sceadu, scead; akin to OS. skado, D. schaduw, OHG. scato, (gen. scatewes), G. schatten, Goth. skadus, Ir. & Gael. sgath, and probably to Gr. sko`tos darkness. √162. Cf. Shadow, Shed a hat. ] 1. Comparative obscurity owing to interception or interruption of the rays of light; partial darkness caused by the intervention of something between the space contemplated and the source of light. [ 1913 Webster ]

☞ Shade differs from shadow as it implies no particular form or definite limit; whereas a shadow represents in form the object which intercepts the light. When we speak of the shade of a tree, we have no reference to its form; but when we speak of measuring a pyramid or other object by its shadow, we have reference to its form and extent.
