Indefinite articles explained
Indefinite articles (articoli indeterminativi) refer to nouns more generally than definite articles and introduce a non-specific noun or concept.
Italian indefinite articles are a similar function to “a” and “an” in English.
In Italian definite articles have different forms according to the following things:
- the gender of the noun (masculine or feminine)
- the first letters of the noun or adjective it precedes
How to say “a/an” in Italian?
English indefinite articles have only two forms (“a” and “an”), while in Italian there are 4 indefinite articles: UNO, UN, UNA, and UN’.
As with definite articles, the rules about selecting the right indefinite article are based on the noun’s spelling and grammatical gender.
They are not based on grammatical numbers, as indefinite articles only have a singular form and are not used with plural nouns.
Tip: indefinite articles are great clues to understand the noun’s grammatical gender!
Indefinite articles: conjugation
- UNO: it is used for all singular masculine nouns beginning with: z, gn, ps, or s+consonant
- UN: it is used for all other singular masculine nouns: nouns that begin with a vowel and nouns that begin with a consonant not included in the exceptions for which uno should be used instead.
- UNA: it is used for all singular feminine nouns beginning with a consonant
- UN’: it is used for all singular feminine nouns beginning with a vowel
You can follow the two tables below for the conjugation of singular and feminine nouns, according to the beginning of the word after the article.
This word is usually a noun, but it could be an adjective too. Please note that un’ (with the apostrophe) is only used with feminine nouns and never with masculine nouns.
