Frequently Asked Questions

Is being infamous always a bad thing?

Infamous has a small range of meanings, and none of them are ones that most people would care to be described with. It may mean "notoriously evil," "disgraceful," or "convicted of an offense bringing infamy" (infamy is "evil reputation brought about by something grossly criminal, shocking, or brutal").

Is infamous the opposite of famous?

Infamous is not the opposite of famous. It does not mean "not famous" or "exceptionally famous." It means "having a reputation of the worst kind." Although the in- prefix often indicates negation or gives a meaning opposite to the word it is attached to, it occasionally will have other meanings, such as "inward" and "thoroughly."

What is the difference between unfamous and infamous?

Although it would appear that both of these words are created by adding a similar prefix to the word famous, they actually have quite different meanings. Infamous means "notoriously evil," whereas unfamous simply means "not famous." Infamous is by far the more commonly-used of the two.
