The official language of the Dominican Republic is Spanish. You will find some bilingual Spanish-English locals, especially in Santo Domingo and the tourist areas. If you speak some Spanish, most Dominicans will do their best to meet and communicate with you. If you have a problem, you can probably find someone who speaks enough English (or probably French and possibly German, Italian or Russian) to help you. Dominicans are quite friendly and will help you if you are polite and respectful. Haitians living in the DR speak Haitian Creole and you may hear some African and Arawakan words mixed with Spanish, especially in rural areas. Communication should not be a problem, even for those who speak minimal Spanish. If you travel to one of the larger all-inclusive hotels, you will have no language problems.
