Forms

razonable m or f (masculine and feminine plural razonables)[1] Old Spanish texts also write rrazonable.[2][3]

Etymology

It is inherited from Late Latin ratiōnābilis (“reasonable; rational”), formed on ratiō (“reckoning; reason”) with the suffix -ābilis.[4][1] Corominas lists it among the derivatives of razón that all the western Romance languages share, and Wiktionary and Wikcionario also analyse it as from Spanish razón + -able.[5][6][1][7]

Its Romance counterparts are Portuguese razoável, Catalan raonable, Occitan rasonable, French raisonnable and Italian ragionevole.[1]

The Latin noun is derived from reor (“to think, reckon”), from Proto-Indo-European *h₂reh₁- (“to think”).[8][1] The original meaning “to count” survives in ratus (“counted; ratified”), and the Germanic cognates include Gothic 𐍂𐌰𐌸𐌾𐍉 (raþjo, “number, account”).[8]

Earliest recorded meaning

The first reliable record in the CDH is the Fueros de Aragón of 1247, which allow a longer delay por alguna razon razonable “for some reasonable cause”, such as witnesses who live far away or are ill.[3] Corominas dates the word only from the end of the 14th century, in López de Ayala's Rimado de Palacio, with the sense “rational”.[5][6]

Semantic evolution

In the 13th century the word meant both “endowed with reason” and “fair, conforming to reason”: the Judizios de las estrellas (1254) divide the signs of the zodiac into mute ones and razonables, the Bocados de oro speak of the alma razonable “rational soul”, and the Partidas use it for what is just.[9][3] The sense “rational” is now obsolete, and the DLE refers it to racional.[4]

The Diccionario de Autoridades added “middling, with some merit in its kind, though not complete”, illustrated with Calderón's ironic Razonables primas tengo “I have passable cousins”.[10] This sense of a fair or moderate amount was already in use in the Americas: in 1519 a spring in Puerto Rico was llena de agua dulce e razonable “full of sweet and decent water”.[11] Today the word means “sensible, in accordance with reason” and “moderate, not excessive”, as of a price or distance.[4][12]
