In aesthetics, nimism is a particular kind of trope or symbol characterized by exaggeration. The term is derived from Latin (nimis), "too much" and (nimietas), excess. Unlike a hyperbole or paradox, it is not applied to linguistic or rhetorical phenomena only, but usually refers to other forms of disparity, e.g. disproportions in sculptures and paintings, or certain sorts of discrepancies in appearance or behaviour (in theatre plays, movies etc.). Thus nimism, by means of symbolic parallels or analogies, is meant to help the reader, viewer etc. to see the truth. A negative nimism hints at something bad (a weakness, vice, sin, crime etc.), the less frequently used positive nimism indicates something good (a virtue or something heroic).
