How to count in Italian



Hi, my name is Ilaria, teacher of Italian L2 / LS at Ellci Milano. In this article we talk about numbers, which are an important part of the lexical baggage of a language: in fact, they serve in many communicative situations, especially at the initial levels. Think about it: without numbers we could not say how old we are, understand a price, buy fruit and vegetables at the market or even simply communicate our address!


Fortunately, unlike other languages, the numbers are not particularly difficult in Italian, because the “irregular” forms are few: if we learn to count up to a thousand, in fact we will discover that the counting proceeds almost always the same way, for all the tens and hundreds.

But let’s see how they are written … nothing complicated, but pay attention to the vowels!


How to write numbers in italian

1 = UNO                              11 = UNDICI

2 = DUE                              12 = DODICI

3 = TRE                               13 = TREDICI

4 = QUATTRO                   14 = QUATTORDICI

5 = CINQUE                       15 = QUINDICI

6 = SEI                                 16 = SEDICI

7 = SETTE                           17 = DICIASSETTE

8 = OTTO                            18 = DICIOTTO

9 = NOVE                            19 = DICIANNOVE

10 = DIECI                          20 = VENTI


After twenty, we start counting again from one, then


21 = VENTUNO                   26 = VENTISEI

22 = VENTIDUE                  27 = VENTISETTE

23 = VENTITRé                   28 = VENTOTTO




An important thing to remember is that if the number 3 in italian is written rigorously without a final accent, its composed numbers instead have it and it is therefore always necessary to write it (even if the pronunciation is practically the same, therefore it is not possible to understand it only through l ‘I listen):








Another important thing regarding the writing of numbers is that, next to the vowels, the last letter of the tens disappears (is eliminated). This time, however, this applies to both writing and pronunciation. The numbers that begin with a vowel are ONE and EIGHT, so it will be TWENTY and TWENTY (and not twenty-one and twenty-eight). This applies to all the tens, which always end with a vowel:










An exception is CENTO (100), where instead the O is pronounced and written. Even with the number eight: we will therefore have to write two O’s in a row.


101 = CENTOUNO                           106 = CENTOSEI

102 = CENTODUE                            107 = CENTOSETTE

103 = CENTOTRE                            108 =CENTOOTTO

104 = CENTOQUATTRO                   109 =CENTONOVE

105 = CENTOCINQUE                      110 =CENTODIECI


The numbers composed of one hundred and from the ten eighty return instead to elide the final vowel ‘O’. So:


180 = CENTOTTANTA                                     680 = SEICENTOTTANTA

280 = DUECENTOTTANTA                        780 = SETTECENTOTTANTA

380 = TRECENTOTTANTA                            880 = OTTOCENTOTTANTA




With 1000 MILLE, there is never an elision. All vowels are always written:


1001 = MILLEUNO, 1008 = MILLEOTTO, 1080 = MILLEOTTANTA, ecc.


To remember, however, the plural of MILLE, which is irregular: it is written MILA. It will therefore be: 


2000 = DUEMILA, 3000 = TREMILA, 4000 = QUATTROMILA, ecc.


Let’s put some order! The ordinal numbers in Italian

writing numbers in italian

What if we have to use numbers to sort things out? How to say the numbers one, two and three at the end of a race, or tell someone the first time we did something, or even just tell which floor we live on in Italian?

In this case the numbers change and become ORDINAL. Let’s see how they are transformed.


1. UNO = PRIMO                                 6. SEI = SESTO

2. DUE = SECONDO                            7. SETTE = SETTIMO

3. TRE = TERZO                                   8. OTTO = OTTAVO

4. QUATTRO = QUARTO                   9. NOVE = NONO

5. CINQUE = QUINTO                      10. DIECI = DECIMO


From eleven onwards it becomes simpler: it is necessary to add -ESIMO to the cardinal number, removing the last letter, so we will have:


11. undicESIMO

12. dodicESIMO, 

13. tredicESIMO

and so on…


The only exceptions are the numbers ending in three, where the final vowel does not fall because it is accented (they lose the accent and are therefore written with two ‘E’: 23. VENTITREESIMO, 33. TRENTATREESIMO, , etc.) and the numbers combined with six, which do not lose the ‘I’ -> 26. VENTISEIESIMO).


Remember that ordinal numbers in Italian are real adjectives, therefore they are used in masculine, feminine, singular and plural, preceded by the article (or preposition) of the corresponding gender.


For example


IL PRIMO GIORNO    – the first day                           I PRIMI GIORNI the first days

LA PRIMA VOLTA        – the first time                        LE PRIME VOLTE the first times


With the preposition


– Dove abiti? Al terzo piano – Where do you live? At the third floor

– Deve girare alla seconda traversa – You must turn at the second side street

– La bolletta va pagata ai primi del mese – The bill must be paid early in the month (lit. the first days of the month)

Alle prime difficoltà ho dovuto rinunciare – – At the first difficulties I had to give up



We said that ordinal numbers in Italian are used in all those situations in which we have to put things in order, in particular for the floors of the buildings, for the rankings of sports competitions but also for the first day of the month, the centuries (ora siamo nel ventunesimo secolo/ now we are in the twenty-first century) and for the names of the popes (Francis first).

In the latter two cases, the numbers are usually written as Roman ((XXI secolo, Francesco I), but must be pronounced precisely as ordinal numbers.


It is also common, in the Italian language, to use the ordinal  millesimo/millesima /thousandth to indicate a generic high or infinite number of times in which we do something.


Or you can use a random high ordinal number: for example, during a discussion, you can hear the phrase è la millesima volta che te lo dico”! O la duecentesima, o l’ottantaquattresima! /it’s the thousandth time I tell you! Or the two hundredth, or the eighty-fourth! Because the Italian language is like this: passion and exaggeration even in numbers!
