Pronunciation

Etymology

It is inherited from Latin nōn (“not”).[2][3][1] In Old Spanish the word was usually Old Spanish non, with ⟨no⟩ beside it: the DEMel counts about 17,800 records of ⟨non⟩ against some 1,700 of ⟨no⟩.[4][1] García de Diego explains the split by stress: ⟨non⟩ was the unstressed form used before the verb, in Old Castilian as in Old Catalan, and ⟨no⟩ the stressed one, which won.[5] Coromines notes the same position effect in Catalan, which otherwise drops final /n/: early texts keep ⟨non⟩ before a verb or a pronoun, as in ⟨non ho farà⟩.[6]

The same Latin word is Portuguese não, Galician non, Catalan no, Occitan non, French non, Italian no and Romanian nu.[7][1][5] In Asturian, non stands before a pause or with words other than verbs, and nun before a verb or an unstressed pronoun.[8][9]

The Latin word probably comes from the older noenum, also written noenu.[10][11] This is usually taken as the negative ne with the neuter of ūnus (“one”), literally “not one”, like nihil from *ne hilum.[12][13][14] Wiktionary calls the origin uncertain: besides Proto-Indo-European *né (“not”) with *óynos (“one”), it mentions a reduplicated *nó-h₁ ne (“not at all”), compared with Gaulish nane (“not”).[1] The same negative is in the Latin words behind ni (from nec), ninguno and nunca (from numquam), and in the learned nulo.[2]

Earliest recorded meaning

Corominas dates the word to about 950.[2] The Cantar de mio Cid (c. 1140, known from a 14th-century copy) has the old form in the Burgos scene: „Conbidarle ien de grado, mas ninguno non osava” “they would gladly have invited him, but nobody dared”.[15] The Auto de los Reyes Magos (c. 1180) already has ⟨no⟩: „No sé quál es achesta strela” “I do not know what this star is”.[15] In both the word is the plain negation of the verb, as today.[15]

Semantic evolution

Over the Middle Ages non gave way to no, the stressed form.[5][4] Alfonso X's prose still writes non, and has no más for “only”.[16] The old form survives in the plural nones: decir nones “to refuse” in the Quijote, and nones “odd numbers”, short for non pares (1276), recorded by 1611.[17][2]

Covarrubias (1611) remarks that in Castilian two negatives deny rather than affirm, unlike Latin, and derives nonada “nothing” from the word.[18] The Diccionario de Autoridades describes it as the particle that denies absolutely, used alone as an answer, in questions that expect a yes, and before a verb followed by nada to strengthen the denial, which it calls a peculiarity of Spanish.[19] Alemany (1917) adds the expletive no of comparisons, where it can be left out without changing the sense.[20] The DLE now also lists its use before nouns and adjectives for the absence or opposite of a quality.[3]

In the Americas the word is recorded from 1493.[21] No más has a wider use in Mexico, Central America and most of South America, while the Antilles, like Spain, use it only for “only”.[22] In Bogotá Cuervo noted the dropping of no after hasta: hasta las doce almorcé for hasta las doce no almorcé “I did not have lunch until twelve”.[23] Román criticised the Chilean habit of ending a sentence with ¿no? to ask for agreement.[24]
