cuajar m (plural cuajares)[1]
Etymology
The word for the abomasum is formed from Spanish cuajo + -ar according to the DLE and the Spanish Wiktionary.[2][3][4] Corominas instead takes it from a noun of Late Latin spelt ⟨coagulare⟩, which Vegetius uses for this part of the stomach.[5][6] Either way the name comes from the milk curdling there in suckling animals, as Autoridades already explained.[6][7]
cuajo is coāgulum (“rennet”), from cōgō (“to gather together”), which is con- with agō (“to drive”).[5][1] Abenbuclárix (c. 1106) already records Mozarabic quwályo for the rennet or rennet stomach of camels.[5]
Earliest recorded meaning
Alfonso X's General Estoria (part I, 1272–1275) names the quaiar as one of the three places where animal fat lies, beside the heart and belly.[8] Corominas dates the noun to the Escorial glossary of about 1400.[5][6]
Semantic evolution
Enrique de Villena's Arte cisoria (1423) tells the carver to pull a pig's cuajar downwards, and Nebrija gives Latin ventriculus.[9][10] The Diccionario de Autoridades defined it as the part where animals take in food, a small bag full of folds, named especially in slaughtered livestock; a picaresque novel mentions a servant running off with a cooked cuajar.[7] The Academy narrowed it to the last of the four stomachs of ruminants in 1884.[4][2]

Forms
cuajar (first-person singular present cuajo, first-person singular preterite cuajé, past participle cuajado)[1] Old Spanish wrote quajar and quaiar;[1][8][7] Autoridades insisted on cuajar with ⟨c⟩ because of the Latin.[1][8][7]
Etymology
The verb for curdling is inherited from Old Spanish quajar, inherited from Latin coāgulō (“to curdle”).[5][6][12][1] Wiktionary sets a syncopated Vulgar Latin *coaglāre between them.[1] The Latin verb is formed from coāgulum (“rennet”), which also gave cuajo.[5][13] The learned doublet is coagular, recorded from 1709.[6][1]
The same verb is Portuguese coalhar, Galician callar, Asturian cuayar, Aragonese cuallar, Catalan quallar, Occitan calhar, French cailler and Italian quagliare.[5][14][1] Corominas has no proof that the Catalan verb was used outside the old Mozarabic territory of Valencia.[5]
Earliest recorded meaning
Corominas dates it to the middle of the 13th century, in the Libro de Alexandre and the Libro de Apolonio.[5][6] In the Alexandre (1240–1250, in a 15th-century copy) the waters ran de la sangre … quajadas, “clotted with blood”.[15][9]
Semantic evolution
In Alfonso X's prose it is already used of liquids setting, of things taking their proper solid form, of a river freezing, and of covering or filling something.[8] The sense “to cover, fill” was common in the Golden Age: in the Americas a river cuajado de indios (México, 1532) was full of people.[16][7] Cuervo traced the history of its senses in detail.[5]
By 1843 the Academy listed the figurative senses “to overload with ornament”, “to succeed, come off” and “to please, suit”.[17] Snow that settles is said to cuajar, and so is fruit that sets.[12] In the Americas there are many local senses: in Mexico, to chat and pass the time, or to tell lies; in Mexico and Central America, to fall asleep; in Puerto Rico, of the coffee plant, to flower.[18][19][20][21]
