Forms

rouă f (uncountable)[1] Old texts write roao, roaă and roa: the Bible of 1688 has „Va fi întru anii aceștea roaoa și ploaie” “there shall be dew and rain in these years” (1 Kings 17:1).[2][3] MDA2 lists the regional variants roauă and rauă and the old roor and ruore.[4]

Etymology

It is inherited from Latin rōs (“dew”), a word that Romanian shares with Occitan ros and Catalan ros.[3][5][4][6][1] It survives in Aromanian aroauă and Megleno-Romanian rauă.[3][7][8] The Latin word comes from Proto-Indo-European *h₁rṓs (“dew, juice”), the source also of Lithuanian rasà.[9]

How the Latin form gave the Romanian one is disputed.[3][1] Candrea's *rōlla is rejected by Ciorănescu and called impossible by the REW.[3][5] Philippide, Pușcariu and Iordan started from a neuter *rōs, with an early Romanian ⟨*ro⟩ lengthened as in zi beside ziuă;[3] Ciorănescu doubts it, since nōs gave noi.[3] Meyer supposed a change of declension, *rovem modelled on bovem, the accusative of the word for “ox”.[3][1] Tiktin, Skok and Graur derived it from *rore with the loss of the second /r/ by dissimilation, which is also the REW's view.[3][5] Ciorănescu finds none of these clear; he suggests that this form became ⟨*roore⟩ and then ⟨*rouri⟩, which was felt as a plural, so that a new singular was made from it.[3][1] The derivatives roura and rouros seem to start from such a plural ⟨*rouri⟩.[3]

Earliest recorded meaning

The first record is in the Psaltirea Hurmuzaki (c. 1500–1520), in a verse on the dew of Hermon that falls on the hills of Zion.[4][10] Coresi's psalter and the Palia of 1581 have it too, the latter in the phrase roa ceriului “the dew of heaven”.[10]

Semantic evolution

The meaning “dew” has stayed the same from the first texts.[10][4] It gave images of freshness and purity: ca roua “fresh, tender; pure”, and pe rouă or pe rouă nescuturată “at first light, before the dew is shaken off”.[6] In a charm quoted by Tiktin, something is bidden to vanish like dew from a flower.[2]

Roua-cerului “dew of heaven” names the sundew (Drosera rotundifolia), whose leaves are covered with sticky drops, and Tiktin also records it for a grass, Glyceria.[6][2] Physics uses temperatură de rouă for the dew point.[6]
