Effect, consequence(s), result refer to something produced by an action or a cause. An effect is that which is produced, usually more or less immediately and directly: The effect of morphine is to produce sleep. A consequence, something that follows naturally or logically, as in a train of events or sequence of time, is less intimately connected with its cause than is an effect: Punishment is the consequence of disobedience. A result may be near or remote, and often is the sum of effects or consequences as making an end or final outcome: The English language is the result of the fusion of many different elements.
