Etymology

Origin of effort

First recorded in 1480–90; from Middle French, from Old French esfort, esforz, derivative of esforcier “to force” ( es- ex- ¹ + forcier force )

Explanation

Effort has to do with how much work you're putting into something. A great achievement can also be considered a great effort. Effort has to do with how hard you're trying. If something is easy, it doesn't take much effort. If it's hard, it takes a lot of effort. Effort is about trying to get something done, even if it doesn't always work out. In sports, coaches don't like losing, but they really hate it when the players aren't giving much effort. There are also large scale, collective efforts, like the effort to cure cancer.
