Checking facts and equipment

The idea

Use comprobar with a thing, or with si or que and a clause. Its stressed present stem changes from o to ue.

Examples

• Compruebo la dirección antes de salir.I check the address before leaving.
• La técnica comprueba el micrófono.The technician checks the microphone.
• Comprobamos si la fecha es correcta.We check whether the date is correct.
• ¿Compruebas las cifras en el informe?Do you check the figures in the report?
• El guardia comprobó la entrada.The guard checked the ticket.
• Han comprobado que funciona la alarma.They have checked that the alarm works.

Watch out

Do not use comprobamos with ue: the first-person plural keeps o.
