Common Mistakes to Avoid
❌ Mistake 1: Using wrong word order
- Tal vez can go at beginning or end
- "Tal vez voy" or "Voy tal vez" - both correct!
- But beginning is more common
❌ Mistake 2: Forgetting that all three "maybes" work
- TAL VEZ = QUIZÁS = A LO MEJOR
- All mean "maybe"
- Choose based on formality!
❌ Mistake 3: Using POSIBLE alone
- Wrong: "Posible voy"
- Right: "Es posible que vaya" OR "Posiblemente voy"
- Need ES or -MENTE ending!
❌ Mistake 4: Overusing subjunctive worry
- For beginners, learn as phrases
- "Tal vez voy" works fine
- Subjunctive comes later!
❌ Mistake 5: Being too certain when unsure
- Use maybe/probably expressions
- Don't say "Sí" if you mean "Tal vez"
- Match certainty to reality!
