Forms

rumiar (first-person singular present rumio, first-person singular preterite rumié, past participle rumiado)[1] Dialect forms include rumear and romiar in Salamanca and rumar in Navarre.[2] Aragonese has remugar, with metathesis, as Catalan does.[3][2]

Etymology

It is inherited from Latin rūmigāre (“to chew the cud”).[3][4][5][1] Corominas derives the Latin verb from rūma (“first stomach of a ruminant”).[3][4] The OLD analyses it as rūmen (“gullet, first stomach”) with the verbal suffix -igō, and records it first in Apuleius and Gargilius Martialis.[6] In Apuleius the verb seems to mean rather “to swallow”.[7]

The verb left descendants in all the Romance languages.[3] They include Portuguese romiar and Occitan romiar, Catalan remugar, Old French rungier, Italian rugumare and Romanian rumega.[8] Coromines explains the Catalan form as a metathesis of an older form with ⟨-umeg-⟩, helped by the prefix re- of repeated action, since the animal chews its food again.[9] The verb French ronger (“to gnaw”) comes from the same Latin word, crossed with a Vulgar Latin verb from rōdō (“to gnaw”).[7][1]

Wiktionary traces the Latin noun to Proto-Italic *roug(s)mən, probably from the root of the verbs for belching, Proto-Indo-European *h₁rewg-, though the origin is disputed.[1]

Earliest recorded meaning

Corominas's first record is the Libro de buen amor of Juan Ruiz, where the poet's go-between eats the meal himself and leaves the lover to chew the cud: él comió la vianda e a mí fazié rumiar “he ate the food and made me ruminate”.[3][4] Alfonso X's General Estoria (1272–1275) has it earlier, of animals that chew the cud, whose fat is called tallow: si fuere de animalia que rumie es sevo.[10][11]

Semantic evolution

The verb has been in general use in every period.[3] Nebrija gave it as Latin rumino, and the figurative sense “to think over slowly” is already in Spanish texts around 1400 and in the American documents of the 16th century: V.S. lo podrá considerar y rumiar (Mexico, 1564).[10][12] The Diccionario de Autoridades gave both senses, the literal one with quotations from Laguna's Dioscorides and the figurative one from Luis de la Puente's meditations.[13] Domínguez noted a pronominal use in 1846, and the Academy marked the figurative sense as colloquial from 1884.[14][15]

The DLE now adds the colloquial sense “to grumble”, and Moliner notes that the verb is often used with a reproachful sense, of brooding over something too long.[5][16] In Bolivia it is used of chewing coca leaves to suck their juice.[17]

Timeline

  • 1726–1739 – the Diccionario de Autoridades records the literal and figurative senses.[13]
