      Lesson details

      Learning outcome

      I can say what I or others are unable to do by using 'nicht' or 'kein' with 'können'.

      Vocabulary and transcripts for this lessons

      Key learning points

      1. 'Können' is a modal verb used to say what you can and cannot do (as in physically or situationally able).
      2. Modal verbs such as 'können' require a 2nd verb in the infinitive, placed at the end of the sentence.
      3. Use part of 'können' + 'nicht' before the infinitive verb to mean 'cannot'/'can't', e.g., 'Ich kann nicht singen.'
      4. Use part of 'können' + 'kein' + noun to mean 'cannot'/'can't', e.g., 'Ich kann kein Haus sehen' - 'I can't see a house'.

      Keywords

      • [au], [äu] - pronounced as in 'Haus' or 'Häuser'

      • Modal verb - verb of necessity or possibility (must, can, want) used with a 2nd verb in the infinitive, which goes to the end

      • Können - a modal verb meaning 'to be able to'

      • Nicht - 'not'

      • Keinen, keine, kein - indefinite articles meaning 'not a'

      Common misconception

      Always use the word 'nicht' to negate a statement.

      Use the correct form of 'kein' to translate 'not a/any' with nouns. Use 'nicht' with verbs and adjectives.

      Teacher tip

      Provide students with a scaffold of the poem so that they have fewer parts to adapt, or let others write their own poems from scratch.
