Questions & Answers about Sento Marco suonare l'assolo, ossia il momento più difficile.

Why does this sentence use the infinitive suonare when the English translation uses the -ing form "playing"?

In Italian, verbs of perception like sentire (to hear) and vedere (to see) are directly followed by an infinitive when you observe someone doing an action. While English often uses the -ing form ("I hear Marco playing"), Italian strictly uses the infinitive construction here: Sento Marco suonare.

Given the current lesson, is Sento Marco suonare an implicit indirect question?

No, although it does use an implicit structure (the infinitive suonare instead of a conjugated verb), it is not a question. An implicit indirect question requires a "wh-" question word before the infinitive, such as Non so cosa suonare (I don't know what to play). Here, suonare simply acts as the action observed by the perception verb sento.

How do you use the word ossia? Is it just a synonym for cioè?

Yes, ossia is a direct synonym for cioè and means "that is," "namely," or "in other words." It is a compound of o (or) and sia (the subjunctive of essere, "let it be"). It is a highly useful word at the B2 level for introducing a clarification or rephrasing something you just said.

The noun used here is l'assolo. Can I just use solo instead?
