Forms

inaccesible m or f (masculine and feminine plural inaccesibles)[1] The early texts write inaçesible, inaccessible and inacessible;[2][3] Autoridades still spelt it inaccessible in 1734.[2][3]

Etymology

It is borrowed from Late Latin inaccessibilis (“unapproachable”), a post-classical word found in Tertullian, Servius and a panegyric of Mamertinus.[4][1][5] Autoridades in 1734 explained it as a compound of the Latin preposition in and accesible, which is recorded from the first half of the 15th century.[3][6]

The Latin adjective is formed from in- (“not”) and accessibilis (“accessible”), from accessus (“approach, entrance”), the participle of accēdō (“to approach”), which is ad- and cēdō (“to go, yield”).[1] The same Latin word is French inaccessible, Italian inaccessibile and Portuguese inacessível (about 1541).[1][7]

Earliest recorded meaning

The first record is in Antonio de Villalpando's Razonamiento de las Reales Armas (1474–1500), in the spelling inaçesible: la inefable & inaçesible luz de la divinidad “the ineffable and inaccessible light of the divinity”.[2] In 1490 Alfonso de Palencia uses it of a place that cannot be reached, a desert.[2]

Semantic evolution

The religious phrase of the inaccessible light in which God dwells recurs in Ambrosio Montesino (1508) and Francisco de Osuna (1527), while Bartolomé de las Casas writes of montes inaccesibles, mountains that cannot be crossed.[2] Autoridades in 1734 defined the word as what cannot be reached, attained or overcome, and gave a moral sense as well;[3][8] Terreros quoted un corazón inaccesible.[3][8] The Academy's 1817 edition added the figurative sense of a person who is hard to approach.[9] Moliner adds the senses “impossible to obtain” and “impossible to understand”.[10] The first record from the Americas is from Buenos Aires in 1680, ynacesibles montes.[11]
