Etymology
It is inherited from Old Spanish egual, inherited from Latin aequālis (“of the same size or age; equal”), from aequus (“flat, smooth, even; equal”).[2][3][4][1] egual is Berceo's usual form, but igual already occurs in some early manuscripts of his works and in 13th-century manuscripts of Alfonso X's astronomy.[2] egual stayed in common use in the 14th and 15th centuries, in Juan Ruiz and the Rimado de Palacio, and the form with i- became general from Nebrija on.[2] Old Spanish also had the verb eguar (“to make equal”), from aequāre.[2]
The same word is Portuguese igual, Catalan igual, Occitan egal, French égal and Italian uguale, beside Old French ivel.[5][1] Meyer-Lübke took Catalan igual for a Castilianism, while Corominas sees no reason for it.[5][2] In his Catalan dictionary he notes that the Catalan form was avoided as vulgar in the Middle Ages, beside egual, and became widespread from about 1480.[6] Judeo-Spanish has Ladino algal.[7]
Earliest recorded meaning
Corominas finds the word first as equal in a charter of 1100 from Oelschläger's list.[8] Berceo has both egual and igual.[2][3] The earliest CDH hit is the Razón de amor (c. 1205–1250), describing a woman's nose: „naryz egual & dereyta” “a nose even and straight”.[9] The Semejanza del mundo (c. 1223) has the i-form, of a sphere „toda ygual e rredonda” “all even and round”.[9]
Semantic evolution
Alfonso X's prose already uses the word for “equal in nature or quantity”, “level, smooth” and “constant, unchanging”, and as a noun for a person's equals.[10] Covarrubias in 1611 recorded the proverb cada qual case con su igual “let everyone marry his equal”, and a use of igual for “better”.[8] Autoridades defined it as matching another thing in quantity, quality or size, and also as “level, without slopes”.[11] The 1884 edition added the equals sign of mathematics and the phrases al igual and de igual a igual.[12]
The adverb “in the same way” is recorded in Venezuela in 1578: „la cebada igual” “and barley likewise”.[13] Modern colloquial Spanish also uses igual for “perhaps”, and the sense “even so, anyway” is common in much of Latin America.[4][14]
