Pronunciation

  • /ˈfeo/, [ˈfe.o][1]

Forms

feo (feminine fea, masculine plural feos, feminine plural feas, superlative feísimo)[1] Old Spanish had hedo, with the usual loss of Latin f-, beside feo.[2] The form hedo is still found in the 15th-century Cancionero de Baena.[3] Asturian has feu and feyo, and Ribagorzan Aragonese fego.[2][4]

Etymology

It is inherited from Latin foedus (“foul, repulsive; ugly”).[5][6][7][8] In Latin the adjective meant “foul, unclean, repugnant”, of looks, taste or smell.[9][10]

Old Castilian had hedo, the regular outcome with h- from Latin f-, but the form with f-, that of most of the Peninsula, took its place in the centre.[2] Wiktionary reports Corominas's view that the Castilian form was borrowed from Asturian feu and displaced the native form.[1] The same Latin word is Portuguese feio and Sardinian feu (Logudorese, also Corsican).[11][12]

De Vaan derives the Latin adjective from a Proto-Italic adjective meaning “afraid”, and further from *bʰeyh₂- (“to be afraid”), if the first meaning was “frightful”.[9] Wiktionary gives the same root.[1] The Latin noun meaning “treaty”, the source of federal, has a separate origin.[13][1]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140) has a fea guisa “shamefully, in a disgraceful way” (verse 1677).[5][14][15] The Tentative Dictionary sums up the Old Spanish senses as “ugly to look at; vile”.[15]

Semantic evolution

Alfonso X's prose already shows the three main senses: lacking beauty (fea color), causing horror or aversion (snoring that is muy feos), and rough or unpolished (stones feos & non polidos).[16] Berceo uses it for “dreadful, horrible”.[17]

The Diccionario de Autoridades (1732) defines it as misshapen and displeasing to the eye, and figuratively of acts and intentions, and records the proverb compuesta no hay mujer fea.[18] From the 19th century the masculine noun un feo means a pointed snub (hacer un feo, dejar feo a alguien); the Academy added it in 1884.[19][20][21]

In much of Latin America feo is said of a bad taste or smell, and works as an adverb, “badly, nastily”.[22][23] In the Dominican Republic it can also mean “abundant, excessive”.[24]
