We often come across books indicating that Trinidad, and in fact, the entire West Indies, is part of North America, rather than South America. But then, Trinidad is not far from Venezuela, and looks more logically like a part of South America. I suspect the inclusion of Trinidad in North America is based on cultural (Trinidad, unlike South America with the exception of Guyana, is English-speaking rather than Romance-speaking) reasons rather than physical. However, if Trinidad is included as South America, should not the rest of the West Indies be considered as part of South America? If not, is it possible to draw a boundary which islands of the West Indies belong to North America or South America?
