💡 Grammar Points
What 'Hicieran' Means
'Hicieran' is the past form of the verb 'hacer' (to do/make) used when the action is uncertain, desired, or hypothetical. It refers to 'they' or 'you plural (ustedes)'.
When to Use the Imperfect Subjunctive
You need this special verb form after a main verb expressing emotion, doubt, or necessity (like 'quería que...' or 'era importante que...') when the main verb is in the past.
❌ Common Pitfalls
Using the wrong mood
Mistake: "Quería que ellos *hicieron* la comida. (Using the Preterite Indicative)"
Correction: Quería que ellos *hicieran* la comida. (Using the Imperfect Subjunctive is required after verbs of desire in the past.)
⭐ Usage Tips
Conditional Sentences
This form is often paired with the Conditional tense ('harían,' 'dirían') to describe impossible or improbable situations: 'Si hicieran esto, harían aquello.'
