Ñangu (NYA-ngoo): (verb) To swim.
"Manñangu i famagu'on gi tasi." = "The kids are swimming at the beach/sea."
"Ya-ña si Sirena ñumangu gi saddok Minondo." = "Sirena (the mermaid) liked to swim in the Minondo river."
"Muñañangu yo' nigap." = "I was swimming yesterday."
Note: "Muñangu" and "ñumangu" are the same word, just different preferences in how to say it (it's easier to say mu- than to put -um- inside). Also, an alternate pronunciation is nangu.
