Perché vs. Siccome: The Difference 

Perché = Why / Because

In Italian, perché is used for both questions and answers:

  • Perché hai chiamato il taxi?
    Why did you call a cab?
  • Perché ero in ritardo.
    Because I was late.

It explains why something happened — the cause.

  • Ho chiamato il taxi, perché ero in ritardo.
    I called a cab because I was late.
  • Non sono andata in spiaggia, perché faceva freddo.
    I didn’t go to the beach because it was cold.

Siccome: Because / Since / As

Unlike in English, you can’t start a sentence with perché in Italian. So:

❌ Perché ero in ritardo, ho chiamato un taxi
❌ Because I was late, I called a cab

That’s not grammatically correct in Italian.

To start a sentence by giving a reason, use siccome instead of perché.

Examples:

  • Siccome ero in ritardo, ho chiamato un taxi.
    Since I was late, I called a cab.
  • Siccome faceva freddo, non sono andata in spiaggia.
    Because it was cold, I didn’t go to the beach.

Why this is hard for English speakers

It’s tempting to use perché or come at the beginning of a sentence because that’s what we do in English. But in Italian, only siccome works in that position.

❌ Perché sono in ritardo, ho chiamato il taxi
✅ Siccome sono in ritardo, ho chiamato il taxi
