Forms

hijastro m (plural hijastros, feminine hijastra, feminine plural hijastras)[1]

Etymology

It is inherited from Late Latin fīliaster (“stepson”), formed from fīlius (“son”) with the suffix -aster.[2][1][3] Medieval Latin used the word for a stepson, a bastard son, a grandson born of a daughter and a son-in-law.[4] The Academy, from 1884, called the word a pejorative of hijo and glossed the Latin masculine and feminine as “son-in-law” and “daughter-in-law”.[5][6] The DCECH lists it among the derivatives of the noun for “son”.[7][8]

The same Latin word is Italian figliastro, Romanian fiastru, French fillâtre, Old Occitan filhastre[3][1] and Galician fillastro.[9]

The Latin word for “son” first meant “suckling”: de Vaan derives it from an adjective formed on Proto-Indo-European *dʰeh₁(i)- (“to suck”).[10][1]

Earliest recorded meaning

The first record is in Nebrija's Spanish–Latin vocabulary of about 1495, where hijastro is explained as “almost a son” and rendered by Latin filiaster.[8][11][12] Old Spanish had said antenado for a stepchild, a word that Berceo uses with this sense.[13][14]

Semantic evolution

Covarrubias in 1611 defined it as the child of a first marriage and paired it with padrastro, as hijastra with madrastra.[15] The Autoridades treated it as a synonym of alnado, with a quotation from Lope de Vega's Peregrino.[16] Terreros gave French beau-fils and Latin privignus, and the Academy defined it from 1817 as the child that one of the spouses brings to a new marriage.[17][18] Moliner lists alnado, antenado and entenado as synonyms.[19] The suffix -astro is the same as in poetastro, a word for a bad poet.[20]

The first records from the Americas are from Ecuador in 1932; a Mexican text of 1940 also calls the extra shoots of a banana plant hijastros.[21]

Timeline

  • 1052 – the older word for a stepchild, antenado, is recorded in a Nájera document as addenantato.[14]
  • c. 1230–1260 – Berceo uses antenado for a stepchild.[13]
  • c. 1495 – Nebrija records hijastro.[8][11]
  • 1611 – Covarrubias pairs it with padrastro.[15]
  • 1726–1739 – the Autoridades defines it as alnado.[16]
  • 1817 – the Academy defines it as the child one of the spouses brings to a new marriage.[18]

  • 1932 – the first record from the Americas, in Ecuador.[21]

Meanings

Noun

  1. stepson;[1] hijastra stepdaughter: the child of one's spouse from an earlier union: Trata a su hijastro como a un hijo más.[2][1]
