💡 Grammar Points

Talking About a Completed Thought: The Preterite Tense

'Pensé' is used for thoughts that happened at a specific point in the past and are now finished. It's like saying 'I had a thought, and it's over.' For example, 'Ayer pensé en la playa' (Yesterday I thought about the beach).

'Pensé' vs. 'Pensaba'

Use 'pensé' for a single, completed thought. Use 'pensaba' (I was thinking / I used to think) for ongoing thoughts in the past, like 'De niño, pensaba que los monstruos eran reales' (As a child, I used to think monsters were real).

❌ Common Pitfalls

Forgetting the Accent Mark

Mistake: "Yo pense que era buena idea."

Correction: Yo pensé que era buena idea. The accent on the 'é' is crucial! It changes the sound and tells you that 'I' did the action in the past. Without it, 'pense' is a different form used for commands or wishes.

⭐ Usage Tips

Expressing an Opinion You No Longer Hold

You can use 'pensé que...' to talk about something you used to believe but now know is different. For example, 'Pensé que eras de México, pero eres de Colombia' (I thought you were from Mexico, but you're from Colombia).

Talking About Intentions

When you follow 'pensé' with another action verb (like 'ir', 'llamar', 'comprar'), it means 'I planned to' or 'I intended to'. For example, 'Pensé ir al cine, pero no tuve tiempo' (I planned to go to the movies, but I didn't have time).

Frequently Asked Questions

What's the difference between 'pensé' and 'pensaba'?

Think of 'pensé' as a snapshot and 'pensaba' as a video. 'Pensé' is for a single, completed thought ('At that moment, I thought it was a good idea'). 'Pensaba' is for ongoing thoughts or beliefs in the past ('When I was young, I used to think...').

Why does 'pensé' have an accent mark but 'pensaste' doesn't?

Great question! In this past tense (the preterite), the accent mark on the last letter for the 'yo' (I) and 'él/ella' (he/she) forms is a rule. It tells you where to put the stress on the word. For other forms like 'pensaste' (you thought), the stress naturally falls in the right place without needing an accent.

Can I say 'Yo pensé en que...'?

Almost! The correct way is 'Yo pensé que...' (I thought that...). You don't need the word 'en' in this case. You use 'pensar en' when you are thinking *about* someone or something, like 'Pensé en mi familia' (I thought about my family).
