Learn Italian: Se lei vincesse, si licenzierebbe per realizzare ogni suo desiderio. - If she won, she would quit her job to fulfill her every wish.

This sentence is a hypothetical "if" clause (the second conditional). In Italian, when you talk about a hypothetical or unlikely present/future event, you must use se followed by the imperfect subjunctive (vincesse), and then the conditional mood for the result (si licenzierebbe).

Why is it "si licenzierebbe" with the reflexive "si" instead of just "licenzierebbe"?

The reflexive verb licenziarsi means "to quit one's job" or "to resign". If you used the non-reflexive licenziare, it would mean "to fire" someone else! Since she is quitting her own job, she needs the reflexive pronoun si.

Why use "per" before "realizzare"?

When you want to express the purpose or reason for an action (meaning "in order to" do something), Italian uses the preposition per followed directly by an infinitive verb.

Normally possessives need an article, like "il suo desiderio". Why is there no article here?

The word ogni (every) replaces the usual article here. Just like in English where you can say "her every wish", Italian allows you to put the possessive directly between ogni and the noun to make ogni suo desiderio.
