The first conditional shows a likely or possible outcome that will probably happen if a certain condition is met.
To form the first conditional we use the formula If + present simple, will + infinitive (without to). Let’s see some examples:
👉 If I study for the test, I will get a good grade → Si estudio para el examen, sacaré buenas notas
👉 If it rains, I won’t go to the park → Si llueve, no iré al parque
👉 She’ll be late if the train is delayed → Ella llegará tarde si el tren se retrasa
👉 She’ll miss the bus if she doesn’t leave soon → Ella perderá el bus si no se marcha pronto
👉 If I have enough money, I‘ll buy some new shoes → Si tengo suficiente dinero, me compraré unos zapatos
