Pronunciation

  • /ˈmjembɾo/, [ˈmjẽm.bɾo][1]

Forms

miembro m (plural miembros, feminine miembro or (proscribed) miembra, feminine plural miembros or (proscribed) miembras)[1] Old Spanish spelt it miembro, mienbro, menbro and myenbro.[2] Old Castilian also had nembro and niembro, and Old Leonese membrio.[3]

Etymology

It is inherited from Latin membrum (“part of the body, limb”).[4][5][1] The Breve diccionario dates it to 1219; the corpus has it in a Castilian text of the Cortes de León dated 1208.[4][6]

The same Latin word is Portuguese membro, Galician membro, Asturian miembru, Catalan membre, French membre and Italian membro.[7][3][1] The French word is described as a borrowing from Latin, and Nascentes calls the Portuguese word learned.[8][1]

The Latin word goes back to *memsro- and Proto-Indo-European *mēms-ro- (“body part, meaty part”).[9] It is related to the words for meat: μηρός (mērós, “thigh”), mėsà (“meat”) and mír (“portion”).[9][10] Wiktionary gives *memzrom and *mḗms (“flesh”).[1]

Earliest recorded meaning

The earliest record in the corpus is a Castilian text of the Cortes de León of 1208, where it is used of the Church as a body: „ansi en la cabeza, como en los miembros” “both in the head and in the members”.[6] In the Fuero de Zorita (1218–c. 1250) it is a limb: a man is to „sea espedaçado por mienbros” “be torn limb from limb”.[6]

Semantic evolution

Alfonso X's Lapidario has the limb, the male member (los miembros … con que fazen linaje) and a part of a whole.[11] Nebrija has several Latin words for the male member, and Covarrubias notes that anything divided into parts has miembros.[12][13] Autoridades gives the physicians' miembros principales (heart, brain, liver and testicles), the members of a moral body such as a city or religious order, and the parts of an architectural order.[14]

The sense “member of a group” was criticised by Capmany in the Cortes of 1810, when it was used of deputies;[15] Baralt defended it in 1855 as good Spanish.[15] An early American record (Tierra Firme, 1518) already speaks of a governor as the head from which the members proceed.[16] In mathematics it is each side of an equation or inequality.[5]

  • 1219 – first record in the Breve diccionario.[4]

  • 1726–1739 – Autoridades gives the medical, moral and architectural senses.[14]
