Pronunciation

  • /moˈleɾ/, [moˈleɾ][1]

Forms

moler (first-person singular present muelo, first-person singular preterite molí, past participle molido)[1]

Etymology

It is inherited from Old Spanish moler, inherited from Latin molō (“to grind in a mill”).[2][3][1] The stressed /o/ became /we/ in the forms stressed on the stem, such as ⟨muelo⟩ and ⟨muele⟩, a change the Autoridades noted as an anomaly of the verb.[4]

The same Latin verb is Portuguese moer, Galician moer, Asturian moler, Catalan moldre, Old Occitan molre and French moudre.[5][1] Catalan had molre at first; the form with an inserted ⟨d⟩ prevails from the 15th century.[6]

The Latin verb is related to mola (“millstone”) and goes back to Proto-Indo-European *melh₂- (“to crush, grind”).[7][1] Its cognates include Ancient Greek μύλη (múlē, “handmill”), Gothic 𐌼𐌰𐌻𐌰𐌽 (malan, “to grind”) and English meal.[7][1]

Earliest recorded meaning

The verb moler is first recorded in a charter of 1161 of the Fitero collection.[8][2] The Fazienda de Ultra Mar (c. 1200, in a 13th-century copy) has it in the plague of the firstborn: troal fijo de la manceba que muele a la muela “down to the son of the maidservant who grinds at the millstone”.[9] The sense was grinding grain.[9][10]

Semantic evolution

In the 13th century the word was used of grinding incense in a mortar (Berceo) and of a stone that crumbles between the fingers (Alfonso X's Lapidario).[9][11][12] Covarrubias defined it as reducing grain to powder, chiefly with the millstone.[10] The Autoridades added two figurative senses, to vex someone gravely, quoting the Quijote, and to tire out, as in estoi molido de trabajar.[4] Terreros noted the painters' grinding of colours and moler a palos “to beat”, and in 1817 the Academy also gave “to chew”, “to wear out (clothes)” and “to beat”.[13][14]

The pressing of sugar cane in the mill gave a special sense: the Canary Islands records speak of mills para moler las cañas from 1500, and Santo Domingo of sugar mills that grind from 1520.[15][16] Malaret and Santamaría record it as an intransitive verb said of the cane, in Cuba, Peru and Puerto Rico.[17][18] In Mexico and Guatemala it means to annoy, in Colombia to work hard, and in El Salvador and Nicaragua it is a vulgar word for having sex.[19][1]
