Grade is a versatile word, and has many meanings. It comes from the Latin ' gradus ', which means 'step'. It should be no surprise then that forms of advancement (such as the incline of hills, grades in school, etc...) are often referred to as a 'grade' (since they are a sort of 'step', or form of advancement, from one place to another).

Grades in engineering (such as the grade of a hillside) are especially important, because they give engineers an idea of how steep the landscape may be, which would then determine different approaches to building or digging.
