Learn Italian: Se trovassimo l'uscita, ne scapperemmo velocemente. - If we found the exit, we would escape from there quickly.

Here, ne is a locative clitic meaning "from there" or "out of it". It replaces a phrase starting with da (from), which in this case refers back to the exit (dall'uscita). It allows you to say "we would escape from it" without repeating the noun.

Could I just say da lì instead of ne?

Yes, you could completely say ...scapperemmo da lì velocemente. However, using ne is much more natural and fluid in Italian when referring back to a place of departure or origin that you just mentioned.

Why do we use trovassimo and scapperemmo?

This sentence is a hypothetical "if" clause. To express an unlikely or imagined situation, Italian uses se + the imperfect subjunctive (trovassimo) in the condition, followed by the present conditional (scapperemmo) for the result. This exactly matches the English structure: "If we found... we would escape".

Why does ne come before the verb?

Like other object pronouns (such as mi, ti, lo, la), the clitic ne usually goes immediately before the conjugated verb it belongs to. Even though in English we say "escape from there", Italian puts the "from there" before the action: ne scapperemmo.
