Forms

miedo m (plural miedos)[1] Old Spanish texts also write myedo and mjedo;[2][3][4] mieo is an old and popular form, and Asturian has mieu.[2][3][4]

Etymology

It is inherited from Old Spanish miedo, inherited from Latin metus (“fear”).[5][6][1][4] The same Latin word is Portuguese medo, Galician medo and Asturian mieu.[4][7]

The Latin noun is reconstructed as Proto-Italic *metu-, but its further origin is unknown.[8][1] Klingenschmitt has compared Old Irish moth (“astonishment”); de Vaan finds the comparison attractive in meaning but notes that it does not explain the sounds.[8][1]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) uses the word several times, mostly in the phrase por miedo de “for fear of”: the door of the Cid's lodging was barred por miedo del rey Alfonso “for fear of King Alfonso”.[5][9][3] The Fuero de Zorita (1218–c. 1250) is the first text whose copy is not later: por miedo de aquella debda “for fear of that debt”.[3]

Semantic evolution

The sense has stayed close to the Latin one: anxiety at a real or imagined danger, and the apprehension that something unwanted will happen;[10][6] Alfonso X's Lapidario already speaks of grand miedo sin razon “great fear without reason”.[10][6] Covarrubias (1611) quotes the definition of the Partidas, in which metus in Latin means fear of death, of bodily torture or of losing one's freedom, and adds that a promise made out of such fear is not valid.[11] That legal notion survives as miedo insuperable, a fear that excuses a crime.[6]

Autoridades records the phrase morirse de miedo and the proverb el miedo guarda la viña “fear guards the vineyard”, that fear of punishment keeps people from crime.[12] In the Canaries los miedos are ghosts or imaginary creatures that frighten children, a sense taken over from Portuguese medo.[13]
