Etymology
It is inherited from Latin mīlle (“thousand”); Old Spanish mil also had the form mill.[2][3][1][4] It has the same form in Portuguese mil, Catalan mil, Asturian mil and Aragonese mil, and the same Latin word is French mille and Italian mille.[4][5] The Latin plural mīlia gave Romanian mie and Old Italian miglia; in Old Catalan accounts mília was the usual form.[5][6] Coromines starts the Catalan word from a Vulgar Latin *mīle.[6] Basque mila was borrowed from Latin.[5]
mīlle goes back to Proto-Italic *smīχeslī, and de Vaan reconstructs Proto-Indo-European *sm-ih₂-ǵʰes-l-ih₂ (“having one thousand”), a compound of “one” and a word for “heap”.[7][1] The closest cognates are Ancient Greek χίλιοι (khílioi, “thousand”) and the Indo-Iranian word for “thousand”, which lack the first element.[7][1] The Roman mile was named mille passus (“a thousand paces”);[2][8] Spanish milla was taken from its plural.[2][8]
Earliest recorded meaning
The first record is in the Cantar de mio Cid (c. 1140, known from a 14th-century copy), where the hero vows „que faga ý cantar mill missas” “that I will have a thousand masses sung there”.[9][10] The DEMel records the forms mill, mil, mille and milia in medieval texts.[11]
Semantic evolution
Covarrubias noted in 1611 that mil is often used for an endless number, as in the wish víviame vuestra merced mil años.[12] The Diccionario de Autoridades recorded that use and the plant name mil en rama, now milenrama “yarrow”, and the joke mil y quinientas for lentils, because so many of them go into a bowl of stew.[13] By 1843 the plural miles was in the dictionary as “thousands”, and Alemany gives the phrase a las mil y quinientas “far too late”.[14][15]
In 16th-century accounts from the Americas mill is common in sums of maravedís, beside cuento for “million”.[16] In Puerto Rico, Ecuador and Chile a mil means “very intensely”, and in Uruguay and Peru it describes a very busy person.[17]
