Etymology

Origin of grade¹

First recorded in 1505–15; from French: “office,” from Latin gradus “step, stage, degree,” derivative of gradī “to go, step, walk”

Origin of -grade²

< Latin -gradus, combining form representing gradus step or gradī to walk. See grade, gradient

Explanation

Grade means "to evaluate or rank," like teachers who grade their students or a food inspector who grades a crop, determining whether it is "food-grade." Grade can be both a noun and a verb. The verb form is used when you grade something, meaning you assign it a value. The actual mark assigned is the noun version of the word grade, such as an A or B. The noun grade can be used to indicate the rank or quality of other items as well, like professional-grade cookware. Grade can also describe the slope of a mountain or road, like a steep grade that is dangerous in bad weather.
