When expressed as numerals, a small superscripted o is added to the respective numbers (1°, 2°, 10°, 100° and so on), corresponding to the English –st, -nd, -rd, and –th.
Numeri dal 1° (1st) al 10° (10th)
| Dal 1° al 10° | |
|---|---|
| 1° primo | 6° sesto |
| 2° secondo | 7° settimo |
| 3° terzo | 8° ottavo |
| 4° quarto | 9° nono |
| 5° quinto | 10° decimo |
Numeri dopo il decimo
- After decimo, ordinal numbers are formed by:
- dropping the final vowel of the cardinal number (except for numbers ending in –tré and –sei);
- adding –esimo.
11° undici → undic- → undicesimo 20° venti → vent- → ventesimo 64° sessantaquattro → sessantaquattr- → sessantaquattresimo 100° cento → cent- → centesimo 500° cinquecento → cinquecent- → cinquecentesimo
- Mille (1000) and numbers ending in –tré and –sei do not drop the final vowel.
trentatré → trentatre- → trentatreesimo cinquantasei → cinquantasei- → cinquantaseiesimo 1000° mille → mille → millesimo
- Ordinal numbers can be abbreviated using Arabic numerals with a superscript o for the masculine and a superscript a for the feminine.
la 2a settimana del 2° semestre
the 2nd week of the 2nd semester - Ordinal numbers are adjectives and agree in gender (masculine or feminine) and number (singular or plural) with the noun that they modify. They normally precede nouns but follow the names of royalty and popes. Roman numerals are frequently used, especially when referring to royalty, popes, and centuries. In such cases, they usually follow the noun.
la prima volta the first time il quarto piano the fourth floor i primi tre capitoli del libro the first three chapters of the book Papa Benedetto XVI (sedicesimo) Pope Benedict the sixteenth
Secoli (centuries)
An ordinal number (or a Roman numeral) + the word secolo is used to indicate centuries:
il primo secolo (I secolo) the 1st century il sesto secolo (il VI secolo) the 6th century il ventunesimo (il XXI secolo) the 21st century
In connection with literature, art, and history, Italian uses the following capitalized forms to refer to centuries from the thirteenth to the twentieth:
il Duecento (il secolo tredicesimo) 13th century il Trecento (il secolo quattordicesimo) 14th century il Quattrocento (il secolo quindicesimo) 15th century il Cinquecento (il secolo sedicesimo) 16th century il Seicento (il secolo diciassettesimo) 17th century il Settecento (il secolo diciottesimo) 18th century l'Ottocento (il secolo diciannovesimo) 19th century il Novecento (il secolo ventesimo) 20th century
Frazioni (fractions)
As in English, the cardinal number expresses the numerator, and the ordinal number expresses the denominator. If the numerator is more than 1, the plural of the ordinal number is used for the denominator.
1/5 un quinto 2/5 due quinti
Half is expressed as mezzo in a fraction; metà is used otherwise.
1/2 un mezzo 4/2 quattro mezzi
metà dei miei amici half of my friends metà della mela half of the apple
NOTE: when mezzo is used as an adjective it agrees with the noun it modifies.
mezza giornata half a day due mezze giornate two half days
