Effectiveness or effectivity is the capability of producing a desired result or the ability to produce desired output. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression. ==Etymology== The origin of the word effective stems from the Latin word , which means "creative, productive, or effective". It surfaced in Middle English between 1300 and 1400 AD. ==Usage== ==Related terms== Efficacy, efficiency, and effectivity are terms that can, in some cases, be interchangeable with the term effectiveness. The word effective is sometimes used in a quantitative way, "being very effective or not very effective". However, neither "effectiveness" nor "effectively" informs about the direction (positive or negative) or gives a comparison to a standard of the given effect. Efficacy, on the other hand, is the extent to which a desired effect is achieved; the ability to produce a desired amount of the desired effect, or the success in achieving a given goal. Contrary to efficiency, efficacy focuses on the achievement itself, not the resources spent to achieve the desired effect. Therefore, what is effective is not necessarily efficacious, and what is efficacious is not necessarily efficient. Other synonyms for effectiveness include: clout, capability, success, weight, performance. Antonyms for effectiveness include: uselessness, ineffectiveness. ==See also== Effect (disambiguation) ==References==
