Etymology

Origin of beneficial

First recorded in 1425–75; late Middle English, from Late Latin beneficiālis, equivalent to Latin benefici(um) “kindness” ( see benefice ( def. )) + -ālis -al 1 ( def. )

Explanation

If it's beneficial, then it's good for you — or for something. Studying is beneficial to your grades. Exercise is beneficial to your health. Spend any time with Italians and you will hear the word bene over and over. It comes straight from Latin, and Italians use it as often as we use "good;" it can mean "fine," "okay," "yummy," or "kind and well behaved." Bene gives us beneficial, but also benefit, beneficent, benevolent and more well-meaning words.
