In Spanish, 'oraciones condicionales reales e irreales' are conditional sentences that talk about what might happen (real) or what could have happened (unreal). They use specific verb forms to show if the condition is possible or impossible.
Use real conditionals to talk about possible or likely situations in the present or future. Use unreal conditionals to talk about hypothetical or impossible situations, either now or in the past.
