Learn Italian: Accidenti! Ho perso il treno.

Literally, accidenti is the plural of accidente (accident or sudden mishap). As an exclamation, it translates to "Damn!", "Darn!", or "Gosh!". It is widely used to express frustration or surprise and is generally considered mild and safe to use in polite company, unlike stronger Italian swear words.

Why does the sentence use perdere (to lose) instead of a verb for "to miss"?

In Italian, you "lose" a train, flight, or bus rather than "miss" it. When talking about missing a form of transportation or an opportunity, you must use perdere. If you used mancare (which means to miss someone emotionally, or to be lacking), it would sound like you are feeling nostalgic about the train itself!

Both perso and perduto are past participles of perdere. Could I say Ho perduto il treno?

Yes, you can! Both perso and perduto are perfectly correct past participles for perdere. However, perso is much more common in everyday spoken Italian, while perduto often sounds a bit more literary, dramatic, or old-fashioned.

Since the current lesson is about exclamations with che, how could I express this same frustration using that pattern?
