Notes on ejercer in the Preterite

Ejercer is fully regular in the preterite. The 'c' stays because it is followed by 'i' or 'e', which naturally produces the soft sound.

Common Mistakes

  • Mistake: Adding a 'z' in the preterite (e.g., 'ejerzí').

    Correct: ejercí

    Why: The spelling change to 'z' only happens before 'o' or 'a'. Before 'i' or 'e', the 'c' already makes the correct sound.
