Frequently Asked Questions
What about 'pienso que'? How is that different?
Great question! 'Pienso que...' (I think that...) is used to state a belief or a factive opinion. Use it to introduce a full clause. For example, 'Pienso que va a llover' (I think that it's going to rain). So, 'pensar de' asks for the opinion, and 'pensar que' states it.
Can I just say '¿Qué piensas?' by itself?
Yes, but it's very general. It means 'What are you thinking?' or 'What's on your mind?'. It's similar to asking '¿En qué piensas?'. If you want to ask for an opinion about a specific thing, you need to add 'de' and the object, like '¿Qué piensas de esto?'.
I heard 'pensar + infinitive' means something different. Is that true?
Yes, that's another common use of 'pensar'. When you follow 'pensar' directly with an infinitive verb (like 'viajar', 'comer', 'estudiar'), it means 'to plan to' or 'to intend to'. For example, 'Pienso viajar a México el próximo año' means 'I plan to travel to Mexico next year'.
