Usage

What does inferior mean? Inferior most commonly means lesser or lower in quality or worth. Inferior is commonly applied to things that are considered not as good as other similar things, especially products. However, inferior is also used to describe how some people are treated as lesser than others. In both cases, it is the opposite of superior, meaning better. Inferior is also used in more specific ways in sciences like anatomy, botany, and astronomy to describe a low position. Example: The new, more expensive model is inferior to the old model in every way—even the packaging is not as good.

Etymology

Origin of inferior

First recorded in 1400–50; late Middle English, from Latin, equivalent to infer(us) “lower” ( cf. under) + -ior comparative suffix

Explanation

You might call something inferior if its quality isn't as good as another, comparable thing, like that kite that you can't get to fly no matter how fast you run back and forth while your friend's kite soars overhead. Besides "lower in quality," another meaning of the adjective inferior is "lower in rank or status," the way a corporal is inferior to a general in the Army. The word inferior can also be used as a noun to mean "a person who is lower in rank or status," in which case you might say to your younger brother, "You are my inferior, therefore you should take out the trash."
