DictionaryinfamousBad reputation
adjective

infamous

IN-fuh-muhs/ˈɪnfəməs/

Well known for something bad or disgraceful.

The infamous swindler is recognized by customers he previously cheated.

A fictional swindler is recognized by two wary former customers beside the same rigged balance used in a small inset; bad reputation tied to an explicit deed, no real-person likeness.
Etymology

These pieces originally suggested “not well-known,” but the word merged with another meaning “of ill repute.” Its modern sense therefore concerns a bad reputation, not a lack of recognition.
