1. complex

   That is complex which is made up of several connected parts. That is compound in which the parts are not merely connected, but fused, or otherwise combined into a single substance. In a composite object the different parts have less of unity than in that which is complex or compound, but maintain their distinct individuality. In a heterogeneous body unlike parts or particles are intermingled, often without apparent order or plan. Conglomerate (literally, globed together) is said of a confused mingling of masses or lumps of various substances. The New England pudding-stone is a conglomerate rock. In a complex object the arrangement and relation of parts may be perfectly clear; in a complicated mechanism the parts are so numerous, or so combined, that the mind can not readily grasp their mutual relations; in an intricate arrangement the parts are so intertwined that it is difficult to follow their windings; things are involved which are rolled together so as not to be easily separated, either in thought or in fact; things which are tangled or entangled mutually hold and draw upon each other. The conception of a material object is usually complex, involving form, color, size, and other elements; a clock is a complicated mechanism; the Gordian knot was intricate; the twining serpents of the Laocoon are involved. We speak of an abstruse statement, a complex conception, a confused heap, a heterogeneous mass, a tangled skein, an intricate problem; of composite architecture, an involved sentence; of the complicated or intricate accounts of a great business, the entangled accounts of an incompetent or dishonest bookkeeper.
