dormitorio m (plural dormitorios)[1]

Etymology

It is borrowed from Latin dormītōrium (“bedroom; dormitory”), one of the learned words that Corominas lists in the family of dormir.[2][3] Wiktionary instead treats it as inherited, through Old Spanish dormitorio, and names the popular dormidero as its inherited doublet.[1]

The Latin noun is the neuter of the adjective dormītōrius (“of or for sleeping”), formed on the stem of the past participle of dormiō (“to sleep”).[1][4] It already meant “bedroom” in imperial Latin, and Christian Latin used it for the common sleeping hall of a religious community.[5] De Vaan traces the verb to Proto-Indo-European *drem- (“to sleep”), a root whose sense “sleep” survives only in Latin and Slavic.[6]

The REW lists French dortoir and Old Spanish dormidor as popular outcomes of the Latin noun.[7] The French word came through dortour.[1][5]

Earliest recorded meaning

Berceo's Vida de Santo Domingo de Silos (c. 1236, in a copy of the late 13th century) lists the rooms of a well-run monastery, with some monks in the church, some in the refectory and otros en dormitorio, “others in the dormitory”.[8][2] Alfonso X's Primera Partida likewise forbids monks to talk in the church, the refectory or el dormitorio.[9][8]

Semantic evolution

Autoridades defined it as the corridor of a convent where the cells are, and explained the name by the older custom of the whole community sleeping in one hall, with the beds separated by curtains or walls; it gave the room for sleeping in a private house as a second sense.[10] The Academy's 1817 edition still put the monastic sense first, then the room in a house.[11] From 1843 the Academy kept only the general sense, “the room meant for sleeping”.[12] Domínguez added the hall of a school or other institution where the beds are set out.[13]

Today the word means a bedroom, and by extension the set of furniture for it;[14][15] ciudad dormitorio is a town whose inhabitants work elsewhere.[14][15] In the Spanish of the United States it also means a student residence, under the influence of English dormitory and dorm.[16] In the Dominican Republic it names a place that lets rooms for the night.[17]
