Italian numbering rules Edit

  • Numbers from zero to ten are specific words, namely zero [0], uno [1], due [2], tre [3], quattro [4], cinque [5], sei [6], sette [7], otto [8], nove [9], and dieci [10].
  • From eleven to sixteen, numbers are formed from the root of the digit followed by ten: undici [11], dodici [12], tredici [13], quattordici [14], quindici [15], and sedici [16]. From seventeen to nineteen, the order is reversed, as the unit is put directly after the ten: diciassette [17], diciotto [18], and diciannove [19].
  • The tens have specific names based on the matching digit root except for ten and twenty: dieci [10], venti [20], trenta [30], quaranta [40], cinquanta [50], sessanta [60], settanta [70], ottanta [80], and novanta [90].
  • Compound numbers are formed by juxtaposing the ten and the unit, causing an apocope of the last vowel of the ten name before a digit starting with a vowel, i.e. one and eight (e.g.: ventuno [21], trentadue [32], quarantotto [48]). When a compound number ends with three, tre becomes tré and the stress is put on the last syllable (e.g.: cinquantatré [53]).
  • The hundreds are formed by prefixing the word hundred by the multiplier digit, except for one hundred: cento [100], duecento [200], trecento [300], quattrocento [400]…
  • Hundreds, tens and units are linked together with no space (e.g.: centonove [109], duecentotrenta [230], novecentonovantanove [999]).
  • Thousands are formed by prefixing the word thousand by the multiplier digit, except for one thousand: mille [1,000] (plural mila), duemila [2,000], tremila [3,000], quattromila [4,000], cinquemila [5,000]…
  • Numbers are grouped in words of three digits, with the specific rule that a space is added after the word for thousand if its multiplier is greater than one hundred and does not end with a double zero (e.g.: duemilatrecentoquarantacinque [2,345], seicentomiladue [600,002], settecentosessantacinquemila duecento [765,200]).
  • Italian language uses the long scale for big numbers where every new word greater than a million is one million times bigger than the previous term. One million is un milione, un miliardo is 109 (the US billion), and un bilione (1012) worths a thousand US billions, the next step, 1015, being un biliardo (one quadrillion).
  • The digit one (uno) becomes un before a masculine noun, which is the case of all scale names. Besides, their plural construction is regular, the ending -e or -o becoming -i (e.g.: un milione [one million], due milioni [two million], un miliardo [one billion], due miliardi [two billion]).
