Forms

claro (feminine clara, masculine plural claros, feminine plural claras, superlative clarísimo)[1]

Etymology

It is inherited from Latin clārus (“loud; bright, clear”); Old Spanish claro has the same form.[2][3][4][1] The initial /kl-/ is unusual: an inherited word would be expected to become ⟨*llaro⟩, with the palatal /ʎ/ of llamar and llave.[1] Corominas places the word in a second layer of Castilian words, in which the group /kl-/ was kept by a later and more conservative treatment, but he does not consider it a learned or semi-learned word.[2] Wiktionary compares clavo, which kept the group in the same way.[1]

The same Latin word is Portuguese claro, Galician claro, Asturian claru, Catalan clar, French clair, Italian chiaro and Romanian chiar.[5][6][1] In Romanian the word became an adverb, “even, just”.[5]

The Latin adjective first meant “loud, sonorous” and then “bright, clear”; de Vaan reconstructs *klāro- (“loud”), from the root of calāre (“to call”) and clāmāre (“to shout”).[7] Wiktionary derives it from Proto-Indo-European *kelh₁- (“to call, shout”) through *kl̥h₁rós.[1] De Vaan points to the same shift from “loud” to “bright” in hel (“loud”) and hell (“bright”).[7]

Earliest recorded meaning

The first record is in the Cantar de mio Cid (c. 1140), where the sun rises bright: „Otro dia mañana, claro salie el sol” “the next morning the sun came up bright”.[8][9] The Cid also calls a sword limpia e clara “clean and shining” and the city Valencia la clara “Valencia the illustrious”.[9][10]

Semantic evolution

Alfonso X's Lapidario already uses claro for what is full of light, easy to see, pure and transparent.[11] Old Spanish also had the senses “blond” (of eyelashes), “unblemished” (of a day or a request) and “clearly” as an adverb.[10] Covarrubias in 1611 opposes it to escuro and gives claro linaje “illustrious lineage” and the title Claros varones “illustrious men”.[12]

The sense “sparse” (of cloth, hair or trees), which the Academy recorded in 1817 with pelo claro and árboles claros, led, Corominas says, to “rare, seldom found”, as in a sixteenth-century continuation of the Lazarillo.[13][2] Cuervo collected classical examples of a voice or sound that is claro “distinct”.[14] The thieves' slang of 1609 used claro for “sky”.[15]

As a noun claro names a clearing in a wood and a short break in the rain, senses recorded in Cuba, Puerto Rico, Honduras and elsewhere in the Americas.[16][17][18] In the sugar mills of Cuba, Mexico and Puerto Rico the clearest froth of the boiling cane juice is called claros; in Peru claro is a clear frothy drink.[19][20] The adverb ¡claro! means “of course”.[1] The word passed into Tagalog as klaro and into German as klaro.[1] Spanish clarín was borrowed by Italian as clarino, whose diminutive clarinetto came back as clarinete in 1780.[3]
