Learn Italian: Non mettiamo le scarpe negli armadi. - We do not put shoes in the wardrobes.

Negli is an articulated preposition, which means it combines in (in) and a definite article (the). Because armadi (wardrobes) is a masculine plural noun starting with a vowel, it uses the article gli. When you combine in and gli, you get negli.

Why do we need le before scarpe if the English translation is just shoes?

In Italian, you usually need to include the definite article (like le for feminine plural nouns) when talking about general items or categories, even though we drop the word the in English. So we say le scarpe instead of just scarpe.

Where is the word for we in this sentence?

It is hidden inside the verb mettiamo! In Italian, the verb ending tells you who is doing the action. The -iamo ending always means we. You do not need to use the pronoun noi (we) unless you want to add special emphasis.

How do we know armadi is plural?

Most masculine nouns end in -o in the singular and change to -i in the plural. The singular word for wardrobe is armadio, so the plural form is armadi.
