Numbers 1–100 in Italian

Numbers from 1 to 100 are a piece of vocabulary you'll use every single day in Italian — telling the time, shopping, giving your phone number, stating your age, catching a bus, reading prices. Learning them solidly at A1 level is a high-impact investment. The first ten are the foundation: uno, due, tre, quattro, cinque, sei, sette, otto, nove, dieci. Eleven through sixteen follow a pattern that combines the digit with -dici: undici, dodici, tredici, quattordici, quindici, sedici. Then from seventeen onward the pattern flips: diciassette, diciotto, diciannove — tens followed by units.

From twenty up, numbers are built predictably: venti (20), trenta (30), quaranta (40), cinquanta (50), sessanta (60), settanta (70), ottanta (80), novanta (90), cento (100). You attach units directly to the tens: ventidue (22), trentacinque (35), settantotto (78), novantanove (99). Two small spelling quirks: when you add uno or otto, the final vowel of the tens drops — ventuno (not ventiuno), ventotto (not ventiotto), trentuno, trentotto, and so on. Also, when a number ending in uno comes before a noun, uno typically apocopates to un: ventun anni (twenty-one years), trentun giorni (thirty-one days).

Numbers are also tied to essential everyday structures. To say your age, you use avere: Ho venticinque anni (I'm twenty-five years old). To tell the time, you use essere: Sono le dieci (It's ten o'clock), È l'una (It's one o'clock), Sono le sei e mezza (It's half past six). Phone numbers are usually read two digits at a time, so 06 456 7890 becomes "zero sei, quattro cinque sei, sette otto, nove zero." Prices take euro without a plural -s (dodici euro, not dodici euros), and decimals use a comma instead of a period in writing (2,50 euro read as due e cinquanta or due euro e cinquanta).

One pronunciation tip that helps enormously: Italian numbers roll together without pauses when said naturally, so trentotto sounds like one word (tren-TOT-to), not tren-ta-ot-to. Also, cento doesn't change form for plurals below a thousand — duecento, trecento, quattrocento — unlike mille, which becomes -mila (duemila, tremila) starting from 2000. The exercises below will give you lots of practice producing and recognizing numbers in speech and writing — counting, age, prices, times, and short dialogues set in shops, restaurants, and train stations. Repetition is the key: by the end you should be able to understand and produce any number from 1 to 100 without any internal translation from your native language, which is the real mark of early fluency.
