Numbers from 0 to 100 - I numeri da 0 a 100

Discover Italian numbers from 0 to 100
You need numbers to count, tell your age, tell the time and much more. But don't worry, with a few tricks and a little practice, you'll be able to remember them in no time! In this lesson I will show you how to memorise numbers from 0 to 100, highlight irregular numbers and explain the rules for forming two-digit numbers.

Numbers from 0 to 10: the foundation

We start with the numbers 0 to 10, which you must learn by heart because they are the basis for all other numbers:

0 - zero
1 - uno
2 - due
3 - tre
4 - quattro
5 - cinque
6 - sei
7 - sette
8 - otto
9 - nove
10 - dieci

Numbers 11 to 19: beware of irregulars

Numbers 11 to 19 do not follow any particular rule and are therefore considered 'irregular'. 

You will notice that from number 11 to 16 they end in '-dici' and from number 17 to 19 they begin with 'dici-'. 

There is no fixed rule, so repeat them often to memorise them!

11 - undici
12 - dodici
13 - tredici
14 - quattordici
15 - quindici
16 - sedici
17 - diciassette
18 - diciotto
19 - diciannove

Two-digit numbers with zero: tens

Numbers ending in zero are very easy to learn. Here are the most important tens:

20 - venti
30 - trenta
40 - quaranta
50 - cinquanta
60 - sessanta
70 - settanta
80 - ottanta
90 - novanta
100 - cento

Regular' two-digit numbers: how to join them

For regular two-digit numbers, you can follow a simple rule: just add the tens (20, 30, 40, etc.) to the numbers 1 to 9, making a kind of 'addition':

Example

20 + 5 = 25 
→ venti+cinque → venticinque
40 + 7 = 47 
→ quaranta+sette→ quarantasette
60 + 9 = 69 
→ sessanta+nove → sessantanove
70 + 4 = 74 
→ settanta+quattro→ settantaquattro

Beware of numbers ending in one and eight

When numbers end with 'uno' (1) or 'otto' (8), you have to be careful because these words start with a vowel in Italian. If they are joined by a ten (which ends with a vowel), the final vowel of the ten is removed:

Example

20 + 1 = 21 → ventuno        ventiuno
30 + 8 = 38 → trentotto       trentaotto
60 + 1 = 61 → sessantuno   sessantauno

Numbers 11 to 19 do not follow any particular rule and are therefore considered 'irregular'.   You will notice that from number 11 to 16 they end in '-dici' and from number 17 to 19 they begin with 'dici-'. Beware of numbers ending in one and eight. When numbers end with 'uno' (1) or 'otto' (8), you have to be careful because these words start with a vowel in Italian. If they are joined by a ten (which ends with a vowel), the final vowel of the ten is removed:  Example  20 + 1 = 21 → ventuno   30 + 8 = 38 → trentotto     60 + 1 = 61 → sessantuno

Practical Exercises

Now that you have learnt the rules, try practising!

  • Count up to 30 aloud.
  • Write the numbers 45, 58, and 91 in Italian.
  • Find examples of numbers ending with ‘uno’ and ‘otto’.

Remember, the key to mastering numbers in Italian is constant practice. Repeat, write and use the numbers in your daily life.
