What is vernacular region that exist near Haiti?

It's important to clarify what you mean by "vernacular region". Vernacular regions are areas where people share a common dialect, culture, or way of life, often defined by their language. Haiti itself has its own distinct vernacular region, with Haitian Creole as its main language.

However, if you're asking about regions neighboring Haiti that share similar vernacular characteristics, here are some possibilities:

* Dominican Republic: Sharing the island of Hispaniola with Haiti, the Dominican Republic also has a strong Creole influence, particularly in the eastern border areas. However, the dominant language is Spanish.

* The Caribbean Islands: The Caribbean is home to a diverse range of languages, including many creoles influenced by French, Spanish, English, and African languages. While not directly bordering Haiti, these islands share a cultural and linguistic heritage.

* Southern Florida: Due to large Haitian diaspora communities, parts of South Florida have incorporated Haitian Creole and cultural elements into their local vernacular.

To give you a more precise answer, please clarify:

* What specific aspects of vernacular are you interested in? (Language, culture, food, music, etc.)

* What is the context of your question? (Research, travel, etc.)
