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.
