Forms

ojo m (plural ojos)[1] Old Spanish wrote oio and ojo; the diphthongised uejo is also old Castilian, and uellos, hueyllo occur in eastern texts.[2][3] Aragonese has uello and güello, Asturian güeyu, and Mozarabic is recorded with forms like welyo.[3][4]

Etymology

It is inherited from Latin oculus (“eye”), in the Vulgar Latin form oclus with the unstressed vowel lost, and Old Spanish already wrote ojo.[5][6][1][7] It is a doublet of the learned óculo.[1]

The same Latin word is Portuguese olho, Galician ollo, Asturian güeyu, Aragonese uello, Catalan ull, French œil, Italian occhio and Romanian ochi.[3][8][1]

The Latin word goes back to *ok(e)lo-, a derivative in ⟨-lo-⟩ of the Indo-European word for “eye”, *h₃ekʷ-; most Indo-European languages have a root noun or an i-stem, so the Latin formation is probably an Italic one.[9] Its cognates include ὄσσε (ósse, “the two eyes”) and akìs (“eye”).[9][10]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) uses the word in its opening lines, as the hero looks back weeping at his house: „De los sos ojos tan fuertemientre llorando” “weeping so bitterly from his eyes”.[5][11] The first record in a text without a later copy is the Fuero de Zorita de los Canes (1218–c. 1250), with a heading on breaking someone's eye.[11]

Semantic evolution

The Latin word already named things shaped like an eye, such as the spot on a peacock's tail and the bud of a vine, and Spanish kept and extended these uses: the eye of a needle, the arch of a bridge, the keyhole, the holes in bread or cheese.[12] Ojo de agua “spring”, recorded about 1280, is a metaphor found in languages of many families, the place where underground water “sees the light”.[5][13] Alfonso X already used ojo alone for a spring in a plain.[14] In the American Southwest ojo is the usual word for a spring and appears in many place names, such as Ojo Caliente.[15]

Autoridades also recorded the sense “evil eye” (now mal de ojo) and “attention, care”, the source of the interjection ¡ojo! “look out!”.[16][17] Derivatives include antojo “whim” (c. 1260), from setting something before one's eyes, and ojeriza “grudge” (1588).[5][12]
