Tips

Finished and Dated Actions

  1. Affirmative: subject + V2. Question/negative: did/didn’t + base. Mark past once.
  2. Los verbos regulares usan -ed; los irregulares deben recuperarse como pareja: buy → bought.
  3. Una fecha es evidencia fuerte de cierre, no un requisito; después de did/didn’t, marca el pasado una sola vez y usa base form.
