When someone asks you perché? (why?), you can recycle the same word in your response because perché also means “because”! Yes, two in one! Let’s look at the following example, where Daniela is asking her students to justify using one article over another. Make sure to look at the context and listen to the inflection!

L'articolo è uno. Uno scontrino, perché?

The article is "uno." "Uno scontrino" (a receipt). Why?

Perché la parola inizia per s più consonante.

Because the word starts with "s" plus a consonant.

So perché actually has two grammatical forms. One is as an adverb meaning “for what reason.” It’s used in forming a question:

Perché avete fatto il nido sulla lampada?

Why did you build a nest on the lamp?

The other grammatical form of perché is a “causal conjunction” meaning “because.” It’s used to introduce the cause when it follows the effect (which might be simply implied as in our first example above). If we use a full sentence to respond to the above question, it might go something like this:

Abbiamo fatto il nido perché a primavera devo fare le uova. (We built the nest on the lamp because in the spring, I have to lay eggs).

In the above example, “I built the nest” is the effect and “I have to lay eggs” is the cause, so perché (because) goes in the middle: effect-perché-cause. 

But here’s the catch. If you want to put the cause first, such as when you’re explaining yourself without being asked, or elaborating on your reasons, then things change in Italian. In English you could technically start your full sentence answer with the cause, using “because.”

Because I have to lay eggs in the spring, we built the nest in the lamp.

However, in Italian you cannot use perché in this case. The word to go to is siccome (because, as, given that, whereas, or since), used exclusively to introduce the cause when it precedes the effect: siccome-cause-effect. Siccome and perché have similar meanings but are not interchangeable within the structure of the sentence. This may seem complicated, but once you get the hang of it, it will become natural. Here’s an example in context, where Lara is explaining her actions to Luca Manara.

Ginevra deve essere iscritta nella lista degli indagati

Ginevra must be recorded on the list of suspects

e deve essere interrogata,

and has to be interrogated,

e siccome non lo fai tu lo faccio io, tutto qui.

and because you're not doing it, I'm doing it, that's all.

In the above example, you could replace “because” with “given that,” "as," “whereas,” or “since.” But you can’t replace siccome with perché!

As your Italian becomes more fluent, you’ll find siccome to be extremely handy when you’re telling stories and explaining things. There are other similar words to call on as well, but we’ll save them for another time.

Learning suggestion:
To get a feel for perché in both of its two contrasting but related meanings, “why” and “because,” check out their occurrences in Yabla videos (and figure out which is which). Do a search with siccome to get acquainted with it, and hear it in context. Then, to really grasp the mechanism, ask yourself some questions, and answer them. Get used to using perché as both the question “why” and the answer “because.” Then, elaborate on your answers using siccome and perché according to how you structure your sentence. Don’t forget the accent on perché!

Here’s a head start:

Perché sei così nervoso?
-Perché... è una storia lunga. Siccome avevo dimenticato di caricare la sveglia ieri sera, stamattina mi sono alzata tardi. E siccome avevo un appuntamento alle nove, non avevo tempo per fare colazione. Farò colazione al bar, perché ora ho fame. Dopo mi sentirò meglio, perché avrò la pancia piena. Siccome la pancia sarà piena, mi sentirò molto meglio.

Why are you so tense?
-Because... it’s a long story. Since I had forgotten to set the alarm last night, this morning I got up late. And because I had an appointment at nine, I didn’t have time for breakfast. I’ll have breakfast at the coffee shop because now I’m hungry. Afterwards I’ll feel better, because my stomach will be full. Since my stomach will be full, I’ll feel better.
