Origin of effect
First recorded in 1350–1400; Middle English, from Latin effectus “the carrying out (of a task, etc.),” hence, “accomplishment, outcome,” equivalent to effec- (variant stem of efficere “to make, carry out”; ef- combining form meaning “out, out from, beyond” + -ficere combining form of the verb facere “do, make”) + -tus suffix of verbal action; cf. ef-, do1
synonym study for effect
1. 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.
