What do Hondurans say to each other when passing on the street
The main language of Honduras is Spanish (and some indigenous languages are spoken, too, but not as much), so they would use the usual Spanish greetings, for example:
-hola! (hi!)
-nos vemos (see you for a goodbye)
-adios (for a goodbye)
Additionally, a number of other greetings can be heard among the younger generation, equivalent to the English (whatsup) - those change more frequently and depend on the group!
