My Thoughts

Articles in Italian

Articles in linguistics are grammatical items that indicate definiteness or indefiniteness and are, therefore, used to convey a degree of specificity about nouns.

Italian articles agree in gender and number with the nouns they refer to and can be divided into two main groups: indefinite articles, which I will discuss here, and definite articles.

Indefinite Articles in Italian

Indefinite articles (articoli indeterminativi) introduce general nouns or concepts. They are the generic counterpart of definite articles and can be translated into English with “a”/”an”.

Just like definite articles, they change depending on the gender (masculine or feminine) and number (singular or plural) of the noun, and sometimes also depending on its first letter.

Here is an overview of how these articles are used in Italian:

  • Uno (used just for singular masculine nouns beginning with z, gn, ps, or s+consonant): uno zaino (a backpack).
  • Un (used for all other singular masculine nouns beginning with a vowel, and with the other consonants): un amico (a friend)

For singular and feminine nouns and adjectives we use:

  • Una(used for all singular feminine nouns beginning with a consonant): una matita(a pencil)
  • Un’ (used for all singular feminine nouns beginning with a vowel): un’amica (a female friend)
Masculine Feminine
Singular Uno studente (student), uno specchio (mirror), uno zaino (backpack), uno psicologo (psychologist) Una borsa (bag), una casa (house), una studentessa (student), una psicologa (psychologist)
Un cameriere (waiter), un sole (sun), un libro (book) Un’ amore (love), un’ attrice (actress), un’ elettricità (electricity)
Un amore (love), un insegnante (teacher), un uomo (man)
Plural Dei camerieri (waiters), dei libri (books) Delle borse (bags), delle case (houses), delle studentesse (students)
Degli insegnanti (teachers), degli uomini (men), degli studenti (students), degli zaini (backpacks)
È un albero.

Important to Remember!

Indefinite articles in Italian are used to generalize about items, people, and topics and are similar to the English “a” and “an”. However, while English indefinite articles vary only depending on the noun spellings, Italian indefinite articles change depending on noun gender and number as well.

Something many people often get mistaken – Italian native speakers included – is the use of un’. Remember this claim and try not to make this mistake: un’ is used with feminine words only!
