Forms

moer (first-person singular present moo, first-person singular preterite moí, past participle moído)[1] Houaiss records mooe in 1365, moer in the 14th century and muy in the 15th.[2] Feijó in 1734 gives the present eu móo, tu móes, elle móe.[3]

Etymology

It is inherited from Latin molō (“to grind in a mill”), written Old Galician-Portuguese moer in the oldest texts.[2][4][5][1]

The same Latin word is Galician moer, Spanish moler, Catalan moldre, Occitan molre and French moudre.[6][1] It passed into Basque as molitu (“to beat”).[6]

The Latin verb goes back to Proto-Indo-European *melh₂- (“to crush, grind”), which also gave mola (“millstone”), the source of mó.[7][1] Wiktionary compares the English meal “ground grain”.[1]

Earliest recorded meaning

Houaiss's first record is mooe, in a text of 1365 from Cunha's slips.[2] The DDGM's glossaries add the Crónica Troiana, where things are ground en poluos “to dust”, and a satirical cantiga about a woman who makes good cheese pastries and knows how to grind and knead.[8][9] The first sense is to grind grain or anything else to powder.[2]

Semantic evolution

Bluteau in 1712 explains moer as crushing with a millstone, and records the painter's pedra de moer for grinding colours and moer alguém com pancadas “to beat someone black and blue”.[10] Barbosa's dictionary of 1611 already has moer-se “to get vexed”.[11] Morais in 1789 adds the sugar mills, where cane is ground to extract its juice, and moer a paciência “to wear down someone's patience”.[12] The figurative senses “to tire out”, “to pester”, “to torment” and “to go over and over in the mind” are all in the modern dictionaries.[2][13][14]

Priberam records a Brazilian sense “to make envious”, and Porto Editora the phrase moer o bicho do ouvido a alguém “to pester someone with requests”.[15][16]
