metro

Italian has three nouns spelled metro: the learned metro of verse and measure, from Latin; the unit of length, from French; and the feminine metro, short for metropolitana.[1][2][3] DELI numbers the first two in this order, and GRADIT puts the unit first.[1][2]

metro1 metre (in verse), measure

Pronunciation

Forms

metro m (plural metri)[3] Old Italian had the feminine plural le metra.[4] Popular forms of the same word survive as Old Paduan medro (a measure of length), Old Marchigian medro (a measure of volume) and Old Friulian miero (1329); in Venice miero was a measure of 25 pounds of oil.[5][6][7]

Etymology

The metre of verse is a learned word, borrowed from Latin metrum, from Ancient Greek μέτρον (métron, “measure”), of Indo-European origin.[1][8][2] Nocentini derives the Greek word from the root Proto-Indo-European *mē- (“to measure”), which also gave mese and misura.[8] The Latin adjective metricus gave metrico, and the noun used for the art of verse gave metrica.[1][8] The word is also French mètre and Spanish metro.[8]

Boccaccio explained the name himself: “dicesi metro da ‘metros’ grece, che in latino suona ‘misura’” (it is called metro from the Greek word, which in Latin means “measure”), because verses are measured by a measure.[1]

Earliest recorded meaning

Nocentini's first date is before 1321, in Dante, who uses the word in its Greek sense “measure”: in Purgatory the fire is so hot that it burns “sanza metro” (beyond measure).[8][4][1] DELI and GRADIT date the metrical sense to the 14th century, with metra in Cecco Nuccoli and metro in Boccaccio, before 1375.[1][2]

Semantic evolution

Dante used the word also for verse and for a way of speaking: “e con paura il metto in metro” (and with fear I put it in verse), and “pur rispuosi lui a questo metro” (I answered him in this manner).[2][9] In 1340 metro is recorded as a measure of capacity of the Levant.[1] Tommaseo's dictionary (1869) has the sense “system of versification”, and Leopardi uses it for a regular beat, comparing thunder to that of a torrent.[1][2]

English borrowed metro (from Italian or Spanish) for a poetic metre in 1619; the word is obsolete there.[10]

metro2 metre (unit of length)

Pronunciation

Forms

metro m (plural metri)[3]

Etymology

The unit of length is borrowed from French mètre (1791), formed from Ancient Greek μέτρον (métron, “measure”).[1][8][2] On 26 May 1791 the Académie des Sciences proposed the new unit as the single measure of length for the whole country, not without opposition.[1]

Earlier, as Migliorini noted, the Italian physicist Tito Livio Burattini of Agordo had used the Greek word for a universal unit in his “Misura universale” (1675): “cavarò prima il mio Metro Cattolico cioè misura universale” (I shall first derive my Universal Metre, that is, universal measure).[1] The derivative metraggio is French métrage, while metratura was formed in Italian.[1][8]

Earliest recorded meaning

The first record is in the proceedings of the assemblies of the Cisalpine Republic, in 1798;[1][8][2][11] GRADIT and Sabatini–Coletti date it to 1801.[1][8][2][11] DELI notes that the date 1791 sometimes given is that of the French word.[1]

Semantic evolution

The metre was defined at first as one ten-millionth of the arc of meridian between a pole and the equator, then by a material standard, and since 1983 by the distance light travels in a fraction of a second.[13][12] The name passed to the measuring rule or tape (1902, Giovanni Pascoli), and figuratively to a standard of judgement (before 1917, Giovanni Boine).[1]

Metraggio was first the measuring in metres (1905) and the quantity of material in metres (1881), and then the length of a film: film a lungo, a corto metraggio is recorded in 1926.[1]

  • 1791 – The French Académie des Sciences proposes the mètre.[1][2]

  • 1881 – Metratura and metraggio are recorded.[1]
  • 1902 – Giovanni Pascoli uses it for a measuring rule.[1]
  • Before 1917 – Giovanni Boine uses it for a standard of judgement.[1]
