Common Mistakes
Mistake: Using 'sumo' for 'I plunge' when referring to a past completed action.
Correct: For a completed action, use the preterite: 'Sumí en el trabajo'. For a current or habitual action, use the present: 'Yo sumo en el trabajo'.
Why: The present tense is for ongoing or habitual actions, not finished ones.
Mistake: Confusing 'sume' (él/ella/usted) with 'sumo' (yo).
Correct: Remember that 'sumo' is 'I plunge' and 'sume' is 'he/she/it/you (formal) plunges'.
Why: These are distinct first and third-person singular forms.
