Word Origin & History

1598, "born out of wedlock," from L. spurius "illegitimate, false" (cf. It. spurio, Sp. espurio), from spurius (n.) "illegitimate child," probably from Etruscan spural "public." Sense of "having an irregular origin, not properly constituted" is from 1601; that of "false, sham" is from 1615.
