Pronunciation

Forms

ralo (feminine rala, masculine plural ralos, feminine plural ralas)[1]

Etymology

It is inherited from Old Spanish ralo, inherited from Latin rārus (“loose-textured, sparse; rare”).[2][1][3][4] Corominas calls it an old dissimilated variant of popular, inherited character: the second /r/ of the Latin word became /l/.[5][6] Its doublet is the learned raro, which the BDELC dates to 1495; the meanings of ralo and raro have been kept apart only since the Golden Age.[3][5][1]

The Academy's dictionaries of 1884 and 1899 derived the word instead from Latin rāllus (“thin, fine”);[7][8][9] Alemany's dictionary of 1917 returned to the etymon given above.[7][8][9]

The same Latin adjective is Asturian ralu, Italian rado, Old French rer and Romanian rar.[10][11] Portuguese has the same dissimilated form, ralo, spelt rralo in the 15th century.[12]

The origin of the Latin adjective is uncertain: it has been compared with Ancient Greek ἐρῆμος (erêmos, “lonely”) and with Lithuanian i̇̀rti (“to dissolve, fall into ruin”), but de Vaan, following Schrijver, finds none of the proposals convincing.[13][1]

Earliest recorded meaning

The first record is in the Moamín, a book of hunting birds in a manuscript of 1250: if a falcon's feathers fail to grow o les nacieren ralas “or grow in sparse”, they are to be anointed with bear's fat.[14][15] The Bocados de oro (c. 1250) and Alfonso X's Partidas follow.[16] The derived verb ralear is already in the Libro de Alexandre.[5][3]

Semantic evolution

Old Spanish used ralo both for “sparse, thin” and for “rare, seldom”; it is the usual form in Juan Ruiz and still in Alfonso de Palencia in 1490.[5] Nebrija treats ralo as the basic form but already accepts raro beside it, in rala cosa o rara and ralas o raras vezes.[5] In the Quijote ralo appears only once, of teeth, while raro is used for “unusual, strange”;[5][17][18] Autoridades keeps the same division, and the Academy marked the sense “rare” as obsolete in 1817.[5][17][18]

In the Americas the word is recorded from 1532, in Mexico, and in 1574 the physician Monardes writes of a lienço ralo, a thin cloth.[19][20] In Mexico some speakers use ralo for “rare”, which Henríquez Ureña explains either as a widening of the sense or as a new dissimilation of raro.[21] Across Central America, Puerto Rico, Peru and Bolivia coffee or an infusion that is too watery is ralo.[22][23] In Cuba the noun names a field of sugar cane with many gaps.[24][5] In the Canaries the word means “runny, not thick”, and una rala is a thin mixture of gofio with water, milk or broth.[25] Judeo-Spanish keeps ralo “rare, sparse”.[26]
