Origin of effect

1350–1400; Middle English < Latin effectus the carrying out (of a task, etc.), hence, that which is achieved, outcome, equivalent to effec- (variant stem of efficere to make, carry out; ef- ef- + -ficere, combining form of facere to do1) + -tus suffix of v. action

1. outcome, issue. 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. 10. achieve, realize, fulfill, perform, consummate.
