Italian Indefinite Articles

The Italian indefinite article (l'articolo indeterminativo) corresponds to English a/an and is used with singular nouns. It also corresponds to the number one.

When the noun to which the article applies is a masculine noun then "a/an" can be translated as "un", or "uno", if the article applies to a feminine noun then the article that has to be used is "una". As the definite articles, there are some rules to understand the use of these articles:

  • uno-UNO: It is used for masculine words beginning with z or s + consonant.

  • un-UN: It is used for all other masculine words, except the cases where you have to use "UNO"

  • una-UNA: it is used with feminine nouns starting with any consonant.

  • un'-UN': It is the elision of una, used when feminine nouns start with any vowel.


un treno e una bicicletta A train and a bicycle
un aeroplano e un’automobile An airplane and a car
uno stadio e una stazione One(an) stage and one(a) station

When plural nouns are indefinite, they simply do not use an article, or they use the partitive form: i.e. cats (no article) or some cats (partitive), coins or some coins (partitive), etc. Partitive will be dealt with further on, so for the time being simply disregard its use.
