Italian indefinite articles

Italian indefinite articles (articoli indeterminativi), which correspond to the English articles a/an, are used when we are thinking of one thing or person we don’t know in a specific way. As we have studied for definite articles, also these articles have different forms related to the gender and the number of the noun they refer to.

Let’s start to see the indefinite articles for masculine nouns.

UN: it is used for masculine nouns, singular that start with consonant or vowel.
For the plural form of indefinite articles, we use the partitive articles (articoli partitivi). They express an approximate quantity and translate the English words some or any. Partitives are formed combining the simple preposition DI with definite articles.
  • un bicchiere / dei bicchieri (a glass glasses)
  • un uccello / degli uccelli (a bird / birds)

UNO: it is used for masculine nouns, singular that start with s + consonant, z, gn, ps, pn, x, y.
