Etymology
Houaiss takes it borrowed from Spanish ría (“arm of a river, river mouth”), which he dates to 1495 and explains as formed from río (“river”) with the feminine ending -a.[2] The Aulete Digital also gives a Spanish source.[3] The Spanish dictionary of the Academy derives its own word from the Spanish word for “river”.[4] Most Portuguese dictionaries derive ria instead within Portuguese, from Portuguese rio: so Nascentes, Silva Bastos, Aurélio, Michaelis, the DLP and the Porto dictionary.[5][6][7][8][9][10] Wiktionary gives both views, an alteration of the Portuguese word or a borrowing from Spanish.[1] The Portuguese record of 1416 is older than the Spanish date Houaiss gives.[2][11]
Portuguese rio goes back through Vulgar Latin *rius to Latin rivus (“brook, stream”).[12]
Earliest recorded meaning
Lorenzo's chronology quotes a text of 1416 with na Ria que ha dauante a dicta çidade “in the ria that lies before the said city”, and the Crónica de D. Fernando has meteromsse em çertas rias que hi ha “they went into certain rias that are there”.[11] The word already named an inlet of water by the coast.[11][2]
Semantic evolution
Vieira (1871–1874) defines the word as the mouth by which a river flows into the sea.[13] The original Caldas Aulete adds a small, navigable branch of a river and, in the plural, a deeply indented coast with shallow sea.[3] Houaiss keeps both senses, a navigable channel or arm of the sea and, in the plural, a coast of this kind, as in the rias of Galicia.[2] The modern dictionaries of Portugal describe the ria in the terms of geography, as a long, narrow inlet where the sea has flooded river valleys.[9][10] Nascentes notes that the name is peculiar to the western coast of the Iberian Peninsula, at Aveiro and Vigo.[5] Aurélio marks the word as used in Portugal.[7]
