Origin

Late Middle English: from Old French degrader, from ecclesiastical Latin degradare, from de- 'down, away from' + Latin gradus 'step or grade'.

grade from early 16th century:
A grade is literally a step from Latin gradus ‘step’, and was originally used in English as a unit of measurement, a use largely replaced by degree, from the same source. The word is also found in graduate (Late Middle English) ‘take a degree’, gradient (mid 19th century), gradual (Late Middle English) ‘done by degrees’, and degrade (Late Middle English). The expression to make the grade is an American expression from the early 20th century.
