inferior

Other forms: inferiors; inferiorly

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.”
