a

Etymology

It is inherited from Latin ad (“to, towards”).^[2][1][3][4] The older form ad is found in Old Spanish, Portuguese, Galician and Catalan.^[5] Hispano-Latin documents, like Italian and Occitan, keep ⟨ad⟩ before a vowel and ⟨a⟩ before a consonant, and Valdés says that the Aragonese of his time still said ⟨ad aquel⟩.^[4]

The same Latin word is Portuguese a, Catalan a, French à and Italian a (also ad); in the western Romance languages it took over the functions of the Latin dative, while in a it survives almost only in adverbial phrases.^[6][4]

ad goes back to Proto-Italic *ad, from Proto-Indo-European *h₂éd (“to, near”); its cognates include Old English æt, Old High German az and the English word at.^[7][1]

Earliest recorded meaning

Latin documents from Spain already use ad as a sign of the dative, as in 762 (ad tibi Munnione Abbati “to you, Abbot Munnio”).^[4] The Cantar de mio Cid (c. 1140, in a 14th-century copy) uses the Spanish preposition for the indirect object, ¡Grado a ti, Señor, Padre que estás en alto! “thanks to you, Lord, Father on high”, and before a personal direct object, Myo Cid ganno a Alcocer “my Cid won Alcocer”.^[8][4]

Semantic evolution

Cuervo traces the uses of a to two groups: direction and movement towards something, from which it became the sign of the dative and of the personal accusative, and nearness and position in place and time, from which come manner, price, instrument and condition.^[4] Latin ad began to be used for in “into” from the 4th century, so that Spanish a covers both, and Late Latin texts of the 6th–7th centuries already use it to mark the dative.^[4] The a before a personal direct object was already usual in the Cid with names of persons and places, and even with the name of a horse (Ensiellanle a Babieca).^[4]

After verbs of movement Old Spanish often put the infinitive without a preposition (exienlo ver “they come out to see him”); this was common until the 15th century, before a became the rule.^[4] Alfonso X's prose uses a for the object of a verb and for direction (ua a fondo “it sinks to the bottom”).^[9] The Academy's 1884 dictionary already lists most of the modern uses, including a before an infinitive with conditional sense (a decir verdad).^[10] In the Canaries a is used popularly for “in, at” (estaba a la ventana).^[11]

Usage notes

A is also a feminine noun, la a (plural aes), the name of the first letter of the alphabet and of the vowel it writes; this is a separate headword in the DLE, with no etymology given.^[14][1][11] The letter is named in Spanish texts from Alfonso X's scientific works on.^[11][9]

Old Spanish texts often write the preposition joined to the article, as al, ala, alas and alos.^[15] Printed texts from the 16th to the 18th century often spell it à.^[13][1]
