💡 Grammar Points
-car Verbs are Tricky
When conjugating '-car' verbs like 'placar', the 'c' changes to 'qu' before 'e' (like in the subjunctive and the 'yo' preterite) to keep the hard 'k' sound.
❌ Common Pitfalls
Forgetting the Spelling Change
Mistake: "Writing 'yo placo' (preterite) or 'que tú places' (subjunctive)."
Correction: The correct forms are 'yo plaqué' (preterite) and 'que tú plaques' (subjunctive) to maintain the pronunciation.
⭐ Usage Tips
Recognizing the Form
If you see 'placas' used as a verb, it is almost certainly addressing one person directly (the 'tú' form) in the present tense.
