Pronunciation

  • Brazil: /ˈmiw/, [ˈmiʊ̯][1]
  • Portugal: /ˈmil/, [ˈmiɫ][1]
  • Portugal, Southern: /ˈmi.li/[1]

Forms

mil m or f[1] Houaiss lists the medieval spellings mill (1328), myl (1365) and mjl (15th century).[2]

Etymology

It is inherited from Latin mīlle (“thousand”), written Old Galician-Portuguese mil in the oldest texts.[2][3][1] The same Latin word is Spanish mil, Catalan mil, French mille and Italian mille; Romanian mie continues the Latin plural mīlia.[4][1]

Nascentes notes that the word did not become ⟨mile⟩, as the sound laws would lead one to expect, because it was used before the noun it counts (proclisis).[5] In the Crónica Geral the word is often written with a stroke through the ⟨l⟩, which its editor thinks may stand for ⟨mile⟩ or ⟨mille⟩.[6]

The Latin word comes from *smīɣeslī, from *smih₂ǵʰéslih₂ (“one thousand”), a compound whose first part is *sm̥- (“one”); it is related to χίλιοι (khílioi) and सहस्र (sahásra).[1][7] De Vaan explains the form as “having one thousand”, and takes the double ⟨-ll-⟩ to be perhaps a sign of a palatal ⟨l⟩.[7]

Earliest recorded meaning

A document of 1258–1261 glossed in the DDGM dates itself era de mil et ducentos et noueenta et noue anos “in the era of one thousand two hundred and ninety-nine years”.[6] Houaiss dates the word to 1265, from Cunha's index of medieval Portuguese.[2] In the cantigas it counts people and things (mais de mil vozes, mil e çento donas “eleven hundred ladies”) and already stands for an endless number, as in mil vezes and mil dias.[6]

Semantic evolution

Besides the exact number, the word has meant “countless” since the medieval lyric (mil cuidos cuidei “I thought a thousand thoughts”), and Morais in 1789 gives the figurative sense with mil, e mil razões.[6][8] The cantigas also have mil tanto “a thousand times as much”.[9] Caldas Aulete records an obsolete use as an intensifier in compounds such as mil-lindo “very pretty”, and Brazilian Portuguese says estar a mil for being full of energy or excitement.[10] The word was borrowed into Papiamentu and Kadiwéu.[1]
