Italian definite and indefinite articles
The definite article “the” in Italian has 6 different forms:
masculine: il (sing), i (plur)
masculine*: lo/l’ (sing), gli (plur)
feminine: la/l’ (sing), le (plur)
* the second form of masculine is used for words that start with s+consonant, z-, ps- y-, gn- and pn- or vowel (in this case lo becomes l’).
For example:
il libro (the book) – i libri (the books)
lo studente (the student) – gli studenti (the students)
la borsa (the bag) – le borse (the bags)
If the word following the article begins with a vowel, la/lo become l’:
l’aereo – the airplane, l’ora – the hour
The forms for the indefinite articles “a/an” are simpler but they follow the same structure:
masculine: un
masculine*: uno
feminine: una/un’
* use this for the same group of masculine words as mentioned for the definite articles
For example:
un treno – a train
uno studente – a studente
una lettera – a letter
The version of the indefinite article with the apostrophe is only used for feminine words starting with a vowel:
un’amica – a friend
