When to Use the Present Subjunctive
You'll use the present subjunctive when the main clause expresses doubt, desire, emotion, uncertainty, or an impersonal opinion about the action in the subordinate clause. For example, 'Espero que custodies bien el paquete' (I hope you guard the package well) or 'Dudo que custodien la verdad' (I doubt they are guarding the truth).
Notes on custodiar in the Present Subjunctive
Custodiar is regular in the present subjunctive. The stem is the same as the 'yo' form of the present indicative ('custodio'), and the endings are flipped (-e for -ar verbs in yo, tú, él/ella/usted forms, and -en for ustedes/ellos/ellas). So, it's custodie, custodies, custodie, custodiemos, custodiéis, custodien.

Common Mistakes
Mistake: Using the present indicative instead of the present subjunctive.
Correct: After verbs like 'esperar', 'querer', 'dudar', use 'custodie' or 'custodies', not 'custodia' or 'custodias'.
Why: These verbs trigger the subjunctive mood to express wishes, doubts, or emotions.
Mistake: Incorrect endings for nosotros/vosotros.
Correct: The forms are 'custodiemos' (nosotros) and 'custodiéis' (vosotros), not 'custodiamos' or 'custodiáis'.
Why: These are specific subjunctive endings that differ from the indicative.
