Pronunciation

  • /nuˈbloso/, [nuˈβ̞lo.so][1]

Forms

nubloso (feminine nublosa, masculine plural nublosos, feminine plural nublosas)[1] A variant ñubloso was used in the 15th and 16th centuries, also in the Americas.[2][3][1]

Etymology

It is inherited from Late Latin nūbilōsus (“cloudy”).[4][1][5] The Latin adjective is formed from nūbilus (“cloudy”) with the suffix -ōsus,[1] and that adjective from nūbēs (“cloud”).[6][1] Beside it Spanish kept nublo, from the simple adjective, first recorded in 1335.[7]

The same family is Asturian nublosu and Portuguese nubloso, which Houaiss records from the 17th century.[8][9] The Latin noun goes back to Proto-Indo-European *(s)newdʰ- (“to cover”).[1] De Vaan compares Welsh nudd (“haze”).[10]

Earliest recorded meaning

The first record is in Alfonso X's Judizios de las estrellas (1254), where it describes a degree of the sky with a “cloudy”, ill-defined star: grado de estrella nublosa.[11][12] The General Estoria (1272–1275) uses it for an overcast, dark sky that clears when Moses appears.[11]

Semantic evolution

The literal sense “covered with clouds” has stayed the same.[4][13] By the 15th century it was also used figuratively of fortune and the times, “adverse, unhappy”: the Diccionario de Autoridades quotes Ayala's la fortuna nublosa y mala.[13] Terreros (1786–1793) already sent the reader to nublado and anublado, and Moliner and the Vox dictionary define it as a synonym of nublado, the usual word today.[14][15][16]

Timeline

  • 1272–1275 – the General Estoria uses it of an overcast sky.[11]
