In Catalan grammar, the conditionals theory refers to the structures used to express hypothetical or unreal situations. There are three main types of conditionals: the zero conditional, the first conditional, and the second conditional.
The zero conditional is used to talk about general truths or scientific facts. It is formed by using the present tense in both the if-clause and the result clause. For example, “If it rains, the streets get wet” translates to “Si plou, els carrers s’humitegen.”
