A grouping of organisms done purely on the basis of shared features and without regard to evolutionary relationships. Grades may include organisms that do not share a common ancestor, or may exclude some organisms having the same common ancestor as the other organisms in the grade. For this reason, many taxonomists do not accept grades as formal classifications. The class Reptilia (reptiles) is a grade since it includes dinosaurs but not birds, even though birds are descended from dinosaurs.

What does -grade mean? The combining form -grade is used like a suffix meaning “walking; moving.” It is very occasionally used in scientific terms, especially in biology. The form -grade comes from Latin gradus, meaning “step,” or Latin gradī, meaning "to walk." These two Latin sources are the root of numerous words in English, from aggressive, degree, and grade to graduate, ingredient, and progress. Check out our entries for these six words to learn more.
First recorded in 1505–15; from French: “office,” from Latin gradus “step, stage, degree,” derivative of gradī “to go, step, walk”
< Latin -gradus, combining form representing gradus step or gradī to walk. See grade, gradient
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.
