Forms

diestro (feminine diestra, masculine plural diestros, feminine plural diestras, superlative diestrísimo or destrísimo)[1]

Etymology

It is inherited from Old Spanish diestro, inherited from Latin dexter (“right, on the right-hand side; skilful”).[2][3][4][1] The feminine continues dextra (“right hand”).[4] Corominas cites the Latin word both in its short forms and in the fuller forms with ⟨-ter-⟩, and explains the sense “skilful” by the skill of the right hand.[2][3]

The same word is Portuguese destro, Galician destro, Asturian diestru, Catalan destre, Occitan dèstre, Italian destro and Old French destre.[5][6][1] French replaced the inherited form with the learned French dextre.[1]

The Latin adjective goes back to Proto-Italic *dekstero- and Proto-Indo-European *deḱs-tero- (“right, right-hand side”).[7][1] Wiktionary compares Ancient Greek δεξιτερός (dexiterós) and δεξιός (dexiós, “right”).[1] Gómez de Silva sees in it the contrastive suffix *-tero-.[8]

Learned words of the same Latin root are ambidextro, dextrina and dextrosa, named because their solutions turn light to the right.[2][3] The word destral “small axe” is dextralis, so called because it is held in the right hand.[2]

Earliest recorded meaning

The first record is in the Cantar de mio Cid, which has mano diestra “right hand” and diestro braço “right arm”, uses the word for a favourable omen, and calls the warhorses cauallos en diestro, led by the bridle while the knights rode their palfreys.[2][3][9] The Tentative Dictionary's earliest senses are “right”, “favourable” and, as a noun, the right hand or side.[10]

Semantic evolution

Alfonso X uses a diestro “on the right” and a diestro y a siniestro “right and left”, and his Estoria de España already has this phrase in the sense “wildly, without aim”.[11] Covarrubias says the word was mostly said of a man who handled arms with skill, and explains llevar de diestro a beast as leading it by the reins in the right hand.[12] The Diccionario de Autoridades notes that the sense “right” was little used because derecho was the common word, and adds the senses “skilful”, “shrewd in business” and “cunning, deceitful”.[13] Cuervo found the sense “right” only in the phrase a diestro y a siniestro.[14]

The Academy's 1884 edition records the noun for a fencer, a bullfighter on foot and the matador, and for the halter or reins of a beast.[15] In the Canary Islands diestro means quick, and as an adverb “fast”: andar diestro is to hurry.[16][17] The first record from the Americas, in 1515, praises a man diestro de canoas “skilled with canoes”.[18]
