The origin of the name Paraguay is uncertain. One version postulates the name takes from Guaran paragu "feather crown" and y "water" thus paragua "feather crown of waters".[14] Other versions affirm that the name derives from the Payagu people,[15] for the Paraguay River was called the Payagu-y, or "river of the Payagus" by the Guaran and hence would have come the name for the country; or that, also from the Guaran, para would mean sea, gua, originates, and y, river, thus Paraguay would mean "river which gives birth to the sea".[16]
