      What I have to do: 'deber' singular persons

      Lesson details

      Learning outcome

      I can use singular persons of the modal verb ‘deber’ to talk about what I have to do.

      Vocabulary and transcripts for this lessons

      Key learning points

      1. The SSC [ca] is pronounced as in 'casa', [co] as in ‘comer’ and [cu] as in ‘cuerpo'.
      2. The modal verb ‘deber’ means ‘must’ and we use it to talk about obligations.
      3. ‘Debo’ means ‘I must’, ‘debes’ means ‘you must’ and ‘debe’ means ‘she, he, it must’.
      4. The modal verb ‘deber’ is followed by an infinitive.

      Keywords

      • Modal verb - a verb of necessity or possibility used with a 2nd verb in infinitive, e.g., must, can, want

      • Deber - a modal verb that means 'to have to/must' with singular forms: ‘debo’ - I must, ‘debes’ - you must, ‘debe’ - she, he, it must

      Common misconception

      When there are two verbs together, we must conjugate both.

      When we have two verbs together, we must conjugate the first one and use the infinitive for the second verb, i.e., 'Debo ayudar con las tareas en mi casa.'

      Teacher tip

      The teacher might want to ask students to create a task timetable. They could write a task for every day of the week, i.e., 'El lunes limpio el suelo con mi madre.'; Los martes hago ejercicio con mi hermano.'.
