Forms
moinho m (plural moinhos)[1] Old Galician-Portuguese wrote moỹo, moyno, moyos and moynhos; the 14th century has moiios, mouios and moio, and the 15th muynho.[2][3] Wiktionary also lists munho.[1]
Etymology
It is inherited from Late Latin molīnum (“mill”), which Houaiss explains as short for Late Latin saxum molīnum (“grinding stone”).[2][3][1][4] García de Diego cites molinum saxum from Tertullian and molinae from Ammianus.[5] Wiktionary takes the noun as the neuter of the adjective molīnus, from molō (“to grind”).[1] The early forms show the loss of the Latin /l/ and /n/ between vowels that is typical of Galician-Portuguese.[2][6]
The same Latin word is Galician muíño, Spanish molino, Catalan molí, French moulin and Italian mulino.[7][1] Portuguese also has moinha and muinha “chaff”.[7]
The verb molō goes back to Proto-Indo-European *melh₂- (“to crush, grind”), which also gave Ancient Greek μύλη (múlē, “mill”), Gothic 𐌼𐌰𐌻𐌰𐌽 (malan) and Lithuanian málti.[8][1]
Earliest recorded meaning
Houaiss dates the word to 1273 from Cunha's medieval index, with the plural moyos in the 13th century;[2][3] Cunha gives moỹo and moyno in the same century.[2][3]
Semantic evolution
The word has always meant both the grinding machine and the building that houses it.[2] Cardoso (1569) glosses it as a water mill, and Bluteau lists the many parts of a mill, the wheel, the paddles, the millstones and the hopper among them.[9][10] Morais (1789) describes it as driven by running water or by the wind.[11] Vieira records the moinho de vento and the figurative fazer vir a agua ao seu moinho, to draw an advantage to oneself.[12]
The word then spread to any grinding machine, such as the coffee or pepper mill, and in Portugal to the olive press and the amount of olives pressed at once.[2][13] Informally a moinho is a glutton, and in Brazil the name of a ribbon dance.[2][14]
