Forms
reino m (plural reinos)[1] Old Spanish wrote both reino and the older regno.[2][1][3]
Etymology
It is borrowed from Latin regnum (“kingship; kingdom”), at first in the Latinising form regno.[2][1][4] García de Diego explains the form with ⟨ei⟩ by the influence of rey.[5] Nascentes suggests the same for Portuguese reino.[6] The same Latin word is Galician reino, Asturian reinu, Catalan regne, French règne and Italian regno.[1][7] The French word is a learned remaking of an older popular form.[8]
The Latin noun is derived from rēx (“king”).[9][10][1] De Vaan reconstructs the Latin word for “king” as Proto-Indo-European *h₃rēǵs (“ruler, king”), with cognates in Old Irish and Sanskrit.[10] The verb reinar, first regnar, was taken from regnō in the same way.[2]
Earliest recorded meaning
In the Cantar de mio Cid (c. 1140, known from a 14th-century copy) the word appears in cerca viene el plazo por el reino quitar “the time limit for leaving the kingdom is drawing near”.[3][2] Corominas also cites the Fuero de Guadalajara and a text of 1219; the Libro de Alexandre has regno.[2] The first record in a contemporary manuscript is the Semejanza del mundo (c. 1223), which speaks of a land with tres rregnos.[3]
Semantic evolution
Alfonso X used it for a kingdom with its people, for any real or imaginary space in which something acts, and for the period of a king's rule.[11] The last use, now covered by reinado, was condemned by Baralt in 1855.[12] The phrase regnos de los cielos appears in Alfonso's laws.[11] Autoridades defined the word as one or more provinces subject to a king, noted the older regno, and added the vassals of a king and the deputies who spoke for the realm in the Cortes.[13]
The 1884 Academy dictionary added the three “kingdoms” of nature, animal, vegetable and mineral, and the DLE now also gives the taxonomic rank of biology.[14][15][16] The figurative sense of a domain or field (el reino de la fantasía) is in Moliner and the DLE.[17][15]
