Forms
espurio (feminine espuria, masculine plural espurios, feminine plural espurias)[1]
Etymology
It is borrowed from Latin spurius (“bastard, illegitimate”), a learned word.[2][3][4][1] Romanian spuriu continues the same Latin word.[5]
The Latin word was a legal term for a child of unknown father, and also a personal name.[6][7] The Oxford Latin Dictionary considers it probably Etruscan, and Gómez de Silva compares the Etruscan family name of similar form and Latin spurcus (“dirty, impure”).[6][7] Wiktionary gives as alternatives the Etruscan word for “public” and a derivation from Proto-Indo-European *sper- (“to scatter”).[1] The Roman jurist Gaius had explained it from Greek σποράδην (sporádēn, “scattered”) or as “sons without a father”, and Covarrubias repeated the Greek etymology.[6][8]
Earliest recorded meaning
The first record is in Alfonso X's Siete Partidas (c. 1256–1265), which explain that a son called espurio may not inherit with the legitimate one, and define him as the child of a woman who gives herself to many.[2][3][9][10]
Semantic evolution
For centuries the word was a legal term for a child of uncertain father: Covarrubias in 1611 and Autoridades in 1732 define it so, and Autoridades adds that the Romans wrote it in abbreviation as S. P., read sine patre.[8][10] Autoridades also gives a figurative sense, “adulterated, corrupt, false”, quoting Sigüenza on letters falsely attributed to Saint Jerome, and the astronomers' sombra espuria for the penumbra of a lunar eclipse.[10] From 1843 the Academy defined the first sense simply as “bastard”.[11] Today the figurative sense prevails: Moliner applies it to anything lacking legitimacy or authenticity, and Vox gives only “false, illegitimate”.[12][13] In the Americas hijos espurios are recorded from 1570 in Nueva Galicia.[14]

The form espúreo, a hypercorrection, is widespread and appears as early as a 1604 printing of Lope's comedies;[2][3] Corominas suspects that many of its instances are printers' errors.[2][3]
