The Wikipedia is very thorough! I’ve got other words to add that also that circulate on the island as well. Starting with a French word because of the Creole ties that the island has- we also say “Chévere!” The word is an expression of “cool.” Part of the reason I also brought up Spain’s relation to other colonies in the Caribbean is because at one point the islands planned to form an alliance akin to states in the United States. Or a confederate union of sorts. Fun fact! This is why Puerto Rico’s flag is inverted to Cuba’s colors for example. Eugenio Maria de Hostos played a huge part in influencing the flag (I think indirectly). He was also an important educator! Born in Mayagüez
here are some more words in Puerto Rican slang to add:
buey - from Spanish it generally means “bull” , in Puerto Rico and other Caribbean islands refers to crabs or a crab(we use it enough here that I think it counts as slang)
hurutongo/ hurutungo viejo - far away /old path
Añoñao/Añoñada- when someone is out of it, tired and perhaps even a little annoyed
changeria - whining and crying
bejuco - another word for “thing” equivalent of “thingagmagig”
diantre, diache - like saying holy crap
parquiar - slang for parking, from the English word itself
With that being said! If Reyna and Hylla do have ties to Cofresi, they might also have familial ties in Dorado. Maybe she’s also visited El Ojo del Buey. And also! Another cool word I think people should be more familiar with- cause Cabezudos are cool and all- but have ya’ll seen Vejigantes?
