Un milion (1.000.000), sau o mie de o mie, este numărul natural care urmează după 999.999 şi este înaintea lui 1.000.001. Denominarea cuvântului milion în toate limbile moderne provine din limba italiană, în care mille înseamnă o mie (1.000), iar milione desemnează o mie mare (1.000.000).

În notaţie ştiinţifică, este scris ca 10⁶. ^[1] Ca o mărime fizică poate fi exprimat folosind sufixul mega din Sistemul Internaţional. Spre exemplu, 1 megawatt este egal cu 1.000.000 watts.

Cuvântul milion este adesea folosit în numeroase limbi ca o metaforă pentru numere foarte mari sau uneori pentru lucruri deosebite, dar şi ca hiperbolă pentru a desemna distanţe, lucruri neobişnuite sau deosebit de mari ("N-aş fi putut să ghicesc asta nici într-un milion de ani"). Titlul scriiturilor lui Marco Polo referitoare la călătoria sa în China poartă titlul de Il Milione, titlu inspirat, se pare, de porecla dată lui Polo datorată povestirilor sale neobişnuite.

The word "million" is common to the short scale and long scale numbering systems, unlike the larger numbers, which have different names in the two systems.

[modifică] Cuvântul milion

In standard English, the -lli- in million is pronounced with an l-sound followed by a y-glide. However, as other languages use a fully palatalized 'l' in this word (such as Italian spells by 'gl'), some English-speakers have picked up this pronunciation, which does not occur elsewhere in the English language but in words of this model.

This word is the most common of words ending in -lion. In American English this can cause spelling confusion due to its double 'll' while words like 'vermilion', 'pavilion', etc. are spelled with a single 'l'. This is not helped by the fact that it does not have a distinct pronunciation.

Million has been abbreviated as both "m" and "mm" in history. The "m" abbreviation is now most common, and the use of "mm" is discouraged.^[2]
