What are the various types of conditional clauses, or "If clauses"/"Si clauses"?

A conditional or "si" clause ALWAYS has two parts: 1) a subordinate clause that contains a condition/hypothesis - this is almost always introduced by the word "if" ("si")2) a main clause that states the consequence of the first (subordinate) clauseThere are 3 types of "si" clause:1) Reality (fact, going to happen) e.g. If you go to the party, I will go as well.Construction: si + present indicative + future So, in Spanish, the e.g.= Si vas a la fiesta, también yo iré2) Possibility (could happen)e.g. If I was rich, I would buy many housesConstruction: si + imperfect subjunctive + conditional So, in Spanish, the e.g. = Si fuera rico, compraría muchas casas3) Impossibility (a past idea that could have happened at the time, but now can't)e.g. If I had studied more, I would have got good gradesConstruction: si + plu-perfect subjunctive + conditional perfectSo, in Spanish, the e.g. = Si hubiera estudiado más, habría sacado buenas notas
