Numbers 0–100
Use number blocks for ages, prices, addresses, and phone numbers.
Understand the choice
Italian numbers build regularly, but ventuno and ventotto show an important sound-saving rule. Practice them in prices and ages, where the noun often remains structurally simple.
Core rule: Compound numbers are written as one word; tens often drop their final vowel before uno and otto.
Notice it in context
Il biglietto costa ventiquattro euro.
The ticket costs twenty-four euros.
Ventiquattro combines venti and quattro; euro is unchanged in the plural.
Mia nonna ha settantuno anni.
My grandmother is seventy-one years old.
Italian uses avere for age; settanta drops a before uno.
La stanza numero trentotto è al secondo piano.
Room number thirty-eight is on the second floor.
Trentotto drops the final a of trenta before otto.
What to remember
- Tre keeps an accent only at the end of compounds: ventitré.
- Uno becomes un before a following noun in many counting contexts, but number labels retain uno.
Common trap: Do not say sono venti anni for age. Say ho vent’anni.
