"They read the books."

Translation: Loro leggono i libri.

[jmbltbrewer]

Why is it "i libri" instead of "il libri?"

[f.formica]

The articles are inflected too: the plural of "il" is "i", and the plural of "lo" is "gli".

Grazie! good to know!

[SibyllaHazel]

the books=i libri, the book=il libro

[Alma3389]

If duolingo says loro leggono libri it is good but when they give me the same english sentence and i write it as duolingo its wrong and they ask me for an article... i dont understant really

[Marninger]

They read = leggono
the books = i libri

They read the books = Leggono i libri

Then it's possible to add "Loro" in the beginning for emphasis, ~ THEY read the books.

[steeveegurl]

In the audio example, they didn't use "i".

[Grace662684]

why 'loro' and not 'sono'?

[MrKittemurt]

Loro means "They".
Sono means "am" or (they) "are".

[Marninger]

When you feel ready there is a lot more to learn about the Italian definite articles at ThoughCo

My answer was right

[PatrolNH]

Why is it that i is in front of libri for Loro leggono i libri but not for leggo libri?

[Marninger]

They read the books = Loro leggono i libri

I read books = Leggo libri
