If certain conditions are met, specific verb forms are used in conditional sentences. For factual conditionals with a present possibility, the simple present is used in both the if-clause and main clause. For possible conditionals, the if-clause uses the simple present and the main clause uses the simple future with will plus the base verb form.

#61: Last week you bought a lottery ticket, but you did not win.
How do we form the third conditional.
Past Perfect talks about an action that was completed before in the past.
From the sentence, I did not win the lottery, so the condition was not true. The condition will never be true because it was already finished. Impossible past condition

In the third conditional, both the condition and the result are impossible.
