Nuance

A subtle difference, distinction, or variation; a subtle quality. Or a sensibility to, awareness of, or ability to express delicate gradations of a meaning (as of an attitude or expression) or of a form (as of its values, textures, or shades, tints, or tones of color, etc.) "Nuance" came to English in the late 18th century, having been "nubes" in Latin, then "nue" in Middle French, each meaning "cloud." In later French, "nue" developed into "nuer" meaning "to make shades of color."(pr. NOO-ahns)Also see brainstorming, creativity, irony, and letterform.
