💡 Grammar Points
The 'Se' Difference
The verb 'olvidar' can be used alone (Tú olvidas...) or with 'se' (Tú te olvidas de...). Using 'te olvidas' emphasizes that the forgetting happened accidentally or that you actively neglected something.
Preposition 'de'
When using 'olvidarse' (the version with 'se'), you must usually follow it with the preposition 'de' before the thing you forgot: 'Te olvidas de la cita' (You forget about the appointment).
❌ Common Pitfalls
Missing the 'de'
Mistake: "Te olvidas la llave."
Correction: Te olvidas de la llave. (When using 'te olvidas', Spanish almost always needs the little word 'de' before the thing forgotten.)
⭐ Usage Tips
Use 'Se' for Accidents
If you want to say something was forgotten accidentally, use 'Se me olvidó' (I forgot it, literally 'It forgot itself to me'). This is much more common than 'Yo olvidé'.

💡 Grammar Points
Direct Object Use
When 'olvidas' means 'to leave something behind,' it acts like a normal verb and takes the forgotten item directly after it, without needing the word 'de'.
⭐ Usage Tips
Context Clues
If the thing being forgotten is a physical object (like a phone or keys), 'olvidas' often means 'you leave it behind.' If it's a memory or a task, it means 'you forget it.'
