What is another word for underworld markets?
Pronunciation: [ˈʌndəwˌɜːld mˈɑːkɪts] (IPA) 
Underworld markets, which refer to the illegal or unofficial trading of goods and services, have many synonyms. Some of these include black markets, shadow economies, grey markets, and illicit markets. The use of these illegal markets is often seen as a symptom of a larger issue, such as economic inequality or government corruption. In recent years, the rise of online marketplaces like the dark web has made it easier for criminal organizations to conduct their activities. Despite efforts to crack down on the underground economies, they continue to thrive in many parts of the world, offering a variety of goods and services that are not always available through legal channels.
