Forms

untuoso (feminine untuosa, masculine plural untuosos, feminine plural untuosas)[1]

Etymology

According to the current Academy dictionary it is borrowed from Medieval Latin unctuōsus (“greasy”), formed from unctum (“ointment, fat”) and the suffix -ōsus.[2][3] Wiktionary allows either that Latin source or a Spanish formation from unto.[1] The Academy's 19th-century editions and Moliner derive it from the noun or from its Latin source.[4][5] Corominas lists it among the derivatives of untar, with a first record in Laguna in 1555 and a rare variant untoso.[6][7]

The Latin noun is the neuter of ūnctus, the past participle of ungō (“to anoint”).[1][8] The verb goes back to *h₃engʷ- (“to anoint”).[1] Wiktionary explains the ending -uōsus by adjectives such as virtuōsus.[1] The same adjective is French onctueux and Italian untuoso.[9]

Earliest recorded meaning

DEMel cites untuoso from a Bible text of about 1400.[10] The Old Spanish Textual Archive has it in the Cirugía mayor of Guido Lanfranco, a manuscript of 1481, in a medical sense: greasy, oily.[11]

Semantic evolution

Terreros glossed it as greasy, as if smeared with fat, and the Academy defined it from 1817 as of a fatty, rich and sticky substance.[12][13] The figurative, disparaging sense, of a manner so sweet and friendly that it seems false and cloying, is a later addition to the dictionaries.[2][1] Today it is also said of a wine or a cream with a smooth, rich texture.[14]

  • c. 1400 – DEMel's first record, in a Bible text.[10]
