Questions & Answers about Se lo sapevo, non venivo alla fiera.
Why are we using the imperfect indicative (sapevo, venivo) instead of the subjunctive and conditional?
This is the imperfetto ipotetico (hypothetical imperfect). In everyday spoken Italian, native speakers frequently replace the complex tense combination used for impossible past conditions (pluperfect subjunctive + past conditional) with the simple imperfect indicative. It's much faster and easier to say in casual conversation.
What is the strictly correct, "textbook" way to say this?
Could "se lo sapevo" also mean "if I knew it" right now?
Does "fiera" just mean "convention"?
Fiera broadly translates to "fair" or "exhibition". Depending on the context, it can refer to a trade show, an expo, a funfair, or a large convention (like Comic-Con or a business expo).
