shade
nounLiterally, the interception, cutting of or interruption of the rays of light; hence, the obscurity which is caused by such interception. Shad differs from shadow, as it implies no particular form or definite limit. whereas a shadow represents in form the object which intercepts the light. Hence when we say, let us resort to 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 extent.
