The whole system in five rules

1.Learn 0 to 19 as words
Nothing below twenty is built by rule a learner can use: undici to sedici put the unit first, diciassette to diciannove put dici first.
2.Tens and units join into one word
venti + due is ventidue; quaranta + sette is quarantasette. No hyphen, no space, no e.
3.Before uno and otto the ten loses its vowel
ventuno, ventotto, trentuno, novantotto. They are the only two units that start with a vowel.
4.A compound ending in tre is written tré
tre on its own has no accent; ventitré, centotré and milletré do, because the stress falls on that last syllable.
5.cento and mille need no un
100 is cento and 1,000 is mille. From 2,000 the thousands use mila: duemila, diecimila. A million is a noun: un milione.

How this site decides a spelling

Most Italian numbers have one spelling. Where usage varies, this site prints the form Treccani’s Enciclopedia dell’Italiano gives as usual and names the other: 108 is printed centootto, and answer keys accept centotto beside it. Every word, from zero to un milione, is produced by one engine and compared letter for letter with a second derivation written separately (3,000,145 checks). How the words are checked lists every decision and its source.

Questions teachers ask

How do you write 21 in Italian?

21 is ventuno, one word. venti loses its final i because uno begins with a vowel, and the same happens to every ten before uno and otto: trentuno, quarantotto, novantuno. Treccani’s Enciclopedia dell’Italiano gives ventuno, "e non ventiuno", as its example of the rule.

Why does ventitré have an accent when tre does not?

Italian marks the accent on a word of more than one syllable that is stressed on its last vowel. tre is a single syllable and needs none; ventitré, trentatré and centotré are stressed on the final tré and take it. Treccani’s entry for tre shows the vowel as closed, which is why the accent is the acute é and not the grave è.

Do Italians write numbers as one word?

Yes, a cardinal number up to the millions is written as a single word: quattrocentosessantotto (468), millenovecentonovanta (1990). milione is the exception because it is a noun and needs its own number in front, so a million is un milione and two million is due milioni.

Where can I get the Italian numbers 1 to 100 as a printable?

The printables page has a one-page A4 PDF of 1 to 100 with the dropped vowels and accented tré marked, and a worksheet generator for any range from 1 to 10 up to un milione. Each worksheet comes with its answer key as a separate PDF.
