The Guianas were originally five countries. But ended up by being three. The three Guyanas were different because they each spoke a different language to the rest of South America. British Guiana (English) Dutch Guiana (Dutch) and French Guiana (French).

This is a matter of language use in non-French speaking countries. It is probably that way to avoid confusion with the other Guianas (there were five separate colonies from different European countries). To the French, French Guiana is simply La Guyane.

How are the Guianas different from the rest of the region
French Guiana is still a French dependency and elects deputies to the National Assembly in Paris. Guyana (formerly British Guyana) and Surinam (Dutch Guiana) are both independent countries.
Both Columbia and Venezuela have experienced more success than The Guianas in their transformation away from a plantation economy. The Guianas are three territories located in north-eastern South America.
The patterns of migration in the Guianas typically involve movement within the region as well as migration from the Caribbean, particularly from neighboring countries such as Suriname, Guyana, and French Guiana. There is also a historical trend of migration to the Guianas from South Asia, particularly from countries like India, to work in industries such as agriculture and mining. Additionally, there is a significant diaspora population in countries like the United States, Canada, and the Netherlands.
The French language is the official language in French Polynesia.
