Common Mistakes
Mistake: Using the imperfect instead of the preterite for a single completed action.
Correct: Use 'expandimos' (preterite) if you mean 'we expanded (once or completed)', not 'expandíamos' (imperfect, meaning 'we used to expand' or 'we were expanding').
Why: The preterite marks a specific, finished event, while the imperfect describes ongoing or habitual past actions.
Mistake: Missing the accent on 'expandió' or 'expandí'.
Correct: The él/ella/usted form is 'expandió' and the yo form is 'expandí', both require accents.
Why: The accent marks the stressed syllable in these preterite forms.
