Paraguay
Etymology

The origin of the name Paraguay is uncertain. One version postulates the name takes from Guaraní paraguá "feather crown" and y "water" thus paraguaí "feather crown of waters". Other versions affirm that the name derives from the Payaguá people, for the Paraguay River was called the Payaguá-y, or "river of the Payaguás" by the Guaraní and hence would have come the name for the country; or that, also from the Guaraní, para would mean sea, gua, originates, and y, river, thus Paraguay would mean "river which gives birth to the sea".
