Pronunciation

Forms

muerto (feminine muerta, masculine plural muertos, feminine plural muertas)[1]

Etymology

It is inherited from Latin mortuus (“dead”) (Vulgar Latin *mortus), the past participle of morior (“to die”).[2][3][4][1] In Spanish it remains the participle of morir, and is also the adjective and the noun “dead person”.[4][5]

The same Latin word is Portuguese morto, Galician morto, Catalan mort, French mort, Italian morto and Romanian mort.[6][7]

De Vaan reconstructs a Proto-Italic *mortwo- “dead” beside *morto-, from Proto-Indo-European *mr̥-uo- (“dead”), a formation of the root of “to die” that also gives Old Irish marb “dead”.[8]

By an old suppletion common in Romance, the word also serves as the participle of matar “to kill”.[2] Corominas finds it from Berceo's Duelo on, in general use in the classical language, and notes that Ibero-Romance and Languedoc share this use most of all.[2][5]

Earliest recorded meaning

Corominas records muerto from the earliest Spanish texts, the Glosas Silenses of the late 10th century; the Cid uses it as the participle of morir.[2][3][9] The Old Spanish Textual Archive has it in a dated text of 1201.[10]

Semantic evolution

Autoridades gave three articles: the participle of morir (with velas muertas “extinguished candles”), the participle of matar, and the noun for a human corpse or a departed soul.[11] The sense “extinguished, put out” gave the derivative amortar “to deaden, put out”.[2] The Academy's 1884 dictionary called the use for matar familiar (He muerto una liebre, “I have killed a hare”) and listed slaked lime or plaster and a figurative “dull, faint”.[12] Moliner records it as a popular use, and also the intensive muerto de miedo, muerto de hambre, muerto de risa.[5] Recent colloquial senses are “worn out”, “tiresome job, burden” and, in cargar con el muerto, “blame, responsibility”.[4][5] In some American countries the noun names, among other things, a speed bump (Costa Rica, Puerto Rico) and a buried fence post (Uruguay).[13]

Timeline

  • late 10th century – the Glosas Silenses.[2][3]
  • c. 1140 – the Cantar de mio Cid uses muerto as the participle of morir.[9]
  • 13th century – Berceo's Duelo uses muerto as the participle of matar.[2]
  • c. 1495 – Nebrija gives Latin mortuus and extinctus.[14]
  • 1726–1739 – Autoridades separates the participles of morir and matar and the noun “corpse”.[11]
  • 1884 – the Academy gives the etymology “Del lat. mortuus” and the slaked-lime sense.[12]
