Bestimmte Artikel: il, lo, la

English has one word for "the". Italian has seven, and the choice depends on three things: the gender of the noun, whether it is singular or plural, and the sound the next word begins with.

• il libro → i libri - the book, the books
• lo studente → gli studenti - the student(s)
• lo zaino → gli zaini - the backpack(s)
• l'amico → gli amici - the (male) friend(s)
• la pizza → le pizze
• l'amica → le amiche - the (female) friend(s)

The article follows the word right after it, which may not be the noun: lo zio (the uncle) but il mio zio; gli amici but i vecchi amici (the old friends). The lo group exists for the sound: il studente would put three consonants in a row, which Italian avoids.

Where Italian uses "the" and English does not

English speakers tend to drop the article where Italian needs it:

• General statements: Il caffè italiano è forte. - Italian coffee is strong. Amo la musica. - I love music.
• Abstract nouns: la libertà - freedom, la pace - peace.
• Languages: L'italiano è bello. - Italian is beautiful. (After parlare it is optional: Parlo italiano.)
• Possessives: la mia casa - my house (literally "the my house").
• Titles, when you talk about someone: Il signor Rossi è qui. - Mr Rossi is here. Speaking to him directly, you drop it: Buongiorno, signor Rossi!
• Countries and regions: l'Italia, la Toscana, il Piemonte - but cities take none: Roma è grande.

Saying *Caffè è buono or *Mia casa è grande is one of the first marks of an English accent in Italian grammar.
