We do not learn language by reading a dictionary, and we do not think or speak in terms of dictionary definitions. Meaning is always more fluid. Nevertheless, we are hemmed in, even trapped, by common usage. Senses we wish to evade entrap us. The greatest escape route is not only humor, but poetry, or art in general. Art does not, of course, liberate us completely from meaning, but it gives a certain measure of freedom, provides elbow room.
