In Galician grammar, the conditional mood is used to express hypothetical or unreal situations. There are two types of conditionals: the simple conditional and the compound conditional.

The simple conditional is formed by combining the infinitive of the verb with the conditional endings -ía, -ías, -ía, -iamos, -iades, -ían. It is used to talk about future actions that depend on a condition, or to express desires, suggestions, or polite requests.

The compound conditional, on the other hand, is formed by combining the past participle of the verb with the conditional of the auxiliary verb “ter” (to have). It is used to talk about actions that would have happened in the past if a certain condition had been met, or to express regrets or unreal situations in the past.

Both types of conditionals are used to introduce a condition, followed by a consequence. For example, “Se chover, non sairei” (If it rains, I wouldn’t go out) or “Se tivese tempo, iría pasear” (If I had time, I would go for a walk).

Learning the conditionals in Galician grammar is essential for expressing hypothetical or unreal situations and mastering the subtleties of the language.
