Pronunciation

  • /raˈθon/, [raˈθõn], /raˈson/[1]

Forms

razón f (plural razones)[1] Old Spanish razón almost always has a voiced -z- (Nebrija, Alfonso de Palencia); raçon occurs now and then as a learned spelling, and rezón, influenced by the prefix re-, is found in a document of 1252.[2]

Etymology

It is inherited from Latin ratio (“calculation, account; reasoning, reason”), through Old Spanish razon.[2][3][4][1] The Latin noun is derived from ratus (“counted, fixed”), the past participle of reor (“to reckon, think”).[2][5][6] De Vaan reconstructs a Proto-Indo-European root *Hreh₁-, whose original sense “to count” survived in the participle.[6]

The word is common to the western Romance languages: Portuguese razão, Galician razón, Asturian razón, Catalan raó, Occitan rason, French raison and Italian ragione.[2][7][1] The Catalan word still had a consonant from Latin /ti/ in radó in the Homilies d'Organyà.[8]

Its learned doublet is ración, which went from “account” to “portion” and is also recorded in the Cid.[2][3][1]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, known from a 14th-century copy) uses it for “words, speech”: „de las sus bocas todos dizían una razón” “from their mouths they all said one thing”.[9][2][3] The Cortes de Benavente of 1202 use it for a party's case or plea: oída la razón también de la mi parte “once the plea of my side too was heard”.[9]

Semantic evolution

Old Spanish already had the senses “words, discourse”, “argument”, “cause” (sin razón) and “order, method”, all in Alfonso X's Lapidario.[10] The 13th-century poem Razón de amor is named after the sense “discourse, poem”.[9] Autoridades adds the act of reasoning, the “reckoning” of time, and fairness in buying and selling, as in póngase en la razón said to someone who asks too much.[11] The modern dictionaries add the mathematical sense “ratio” and the colloquial “message”.[4]

In Puerto Rico, León and Asturias razón means “message, word sent”.[12][13][14] In Chile it is each turn of a payador in a sung contest.[15] Baralt condemned perder la razón and matrimonio de razón as French.[16]
