Usage
What does infamous mean? Infamous means having, deserving, or resulting in a bad or evil reputation. The word is typically used to describe people, actions, and events. It’s especially used in the context of violent crimes, scandals, and tragedies. Infamous is often used interchangeably with the word notorious, which most commonly means famous or well-known for a negative reason. But infamous is also sometimes used in a more general way to describe things, such as behavior, as shameful, shocking, detestable, vile, heinous, or scandalous. The state of quality of being infamous is infamy. Example: The infamous bank robber was known for setting fire to the crime scene while making his escape.

Etymology
Origin of infamous
First recorded in 1350–1400; Middle English, from Latin infām(is) ( see infamy) + -ous
Explanation
Someone who is infamous has a very bad reputation. If you become a Hollywood star and find yourself on the pages of gossip magazines for your affairs and addictions, you will have succeeded in becoming infamous. Infamous is from Latin infamis, for negative fame. If you're bad but unknown, then you're not infamous — it's reserved for those wicked and well-known people that capture our collective imagination. It is a strong and resonant term. Some synonyms are notorious, disgraceful, and odious. The stress is on the first syllable.
