✕Common Mistakes

  • Ich hab die ganze Nacht lernen.

    After "hab" you need the past participle, not the infinitive.

  • Ich hab die ganze Nacht gelernt.

    The apostrophe is optional; beginners often omit it, but it signals the missing "e" in spoken form.

  • Ich hab der ganze Nacht gelernt.

    Do not use the dative "der ganzen Nacht" here; the phrase functions as an accusative object of duration.

Cultural Tip

The contraction "hab" is typical of everyday spoken German and is common among younger speakers. In formal contexts—emails, essays, or presentations—use the full form "habe". Also, Germans often add "durch" ("die ganze Nacht durch") for extra emphasis, especially when the night felt especially long.
