Forms

râu n (plural râuri)[1] In the Moldovan Cyrillic alphabet the word is written рыу.[1]

Etymology

It is inherited from Vulgar Latin *rius (“river”), the spoken form of Latin rīvus (“brook, small stream”).[2][3][1] MDA2, DLR and DEX give the etymon as the classical form.[4][5][6] Ciorănescu cites Pușcariu's EWRS (no. 1469) and the REW for this etymology.[2] The Latin word goes back to Proto-Indo-European *h₃rih₂wós, from the root *h₃reyh₂- (“to flow, set in motion”);[1] de Vaan reconstructs the same Proto-Indo-European adjective with the sense “whirling”.[7]

The word survives south of the Danube: Aromanian arãu and Megleno-Romanian rou.[2][8] Its Romance cognates include Italian rio, Sardinian riu, Occitan riu, Catalan riu, Spanish río and Portuguese rio.[2][1]

Earliest recorded meaning

Tiktin dates the first record to 1377, citing Drăganu's collection of early names.[9] In Romanian texts it appears in the Psaltirea Hurmuzaki of the early 16th century, with the sense “river”: „Riul lui Dumnedzău împlu-se de apă” “the river of God is full of water” (Psalm 64:10).[5][4]

Semantic evolution

The main sense is a large flowing water formed by several streams.[6][4] Old texts also used it for a spring and for a torrent of water, senses now obsolete.[4] From the image of flowing water came “a stream of liquid” and, figuratively, a long column of people; the adverbial râuri-râuri “in streams, in great numbers” is used by Eminescu of peoples set in motion.[6][9] Ion Neculce wrote that blood flowed in the streets “like rivers”.[9]

In the plural the word names the wavy lines of embroidery on the sleeves and front of the peasant blouse; in Oltenia this sense has the form răuri.[6][9][4] In parts of Transylvania Râu is the local name of the Arieș river.[10] Ciorănescu explains the derivative înrâuri “to influence” as a loan translation of French influer, compare German Einfluss.[2]
