A "house of ill-fame" is a term used to describe a brothel or a house of prostitution. There are several synonyms for this term, including whorehouse, prostitute den, brothel, and bawdy house. These terms are often used in a negative context to refer to places where women are forced into prostitution or where illegal activities are carried out. However, some people argue that these places can also provide a safe environment for sex workers and should be recognized as legitimate businesses. Despite these debates, "house of ill-fame" remains a commonly used term for such establishments.
