Forms
rău m or n (feminine singular rea, masculine plural răi, feminine/neuter plural rele)[1]
Etymology
It is inherited from Latin reus (“defendant, accused”), which came to mean “guilty” and then “bad”.[2][3][4][1] Wiktionary sets the sense “bad” in Late Latin.[1] Pușcariu notes that the step from “guilty” to “bad” is easy and that Romanian shares it with Italian dialects.[4] Șăineanu put it in moral terms: the culprit became the type of wickedness.[5] De Vaan defines the Latin word as “party in a lawsuit, defendant” and, with Walde and Hofmann, connects it with rēs (“thing, case”).[6]
The word survives in all four branches: Aromanian arãu, Megleno-Romanian rǫu and Istro-Romanian rewu.[2][7][8] The inherited Romance cognates with the same sense are Dalmatian ri and Italian rio (“wicked”).[2][9][1]
Earliest recorded meaning
Tiktin's first record is a document of 1490.[10] In Romanian texts the word appears in the Psaltirea Hurmuzaki of the early 16th century, where the feminine rea occurs.[11][3] Coresi's psalter of 1570 already has the masculine rău in dozens of verses.[12]
Semantic evolution
From the start the word covered both a quality (“bad, wicked”) and, used as a noun, “evil”.[3][10] In the Lord's Prayer of a 1746 Gospel book, „ne izbăvește pre noi de cel rău” means “deliver us from evil”.[10] MDA2 also records the masculine noun for “evil spirit” and the curse a da tuturor răilor “to give someone to all the devils”.[3]
The adverb developed the sense “strongly, very”.[13][1] Pușcariu compared this with Albanian keq (“bad; badly”), which has the same double use.[4] Ciorănescu adds the noun senses “harm”, “damage” and “illness”.[2] DEX lists rău de mare “seasickness” and rău de munte “altitude sickness”.[13]
