Other forms: superiors; superiorly
The salesman boasted to his customer that the $1 million car was well worth the price because it was far superior, meaning of higher quality, to any car that had come before it. This car, the salesman bragged, could fly.
Superior comes from the Latin word meaning above and it literally means something that is above others in quality or status. Sometimes being superior can be perceived as a negative, as in the woman who acts superior to all of her friends, having a high opinion of herself just because she has millions of dollars in the bank after winning the lottery.
