I will think about it
A slightly more direct or formal way to say it, using the simple future tense. Common in both writing and formal speech.
Means 'Let me think about it.' A common and slightly softer way to ask for time to consider something.
Means 'I have to think about it,' implying it's a necessary step before you can give an answer.
Means 'I need to think about it.' Very similar to 'Tengo que pensarlo' but focuses on the need rather than the obligation.
Do you want to buy the shoes? —Hmm, I'm going to think about it. They're a little expensive.
Are you coming to the party with us? —Let me think about it and I'll let you know later.
It's an important decision. I have to think about it carefully before answering.
Do you accept our offer? —I will think about it over the weekend and call on Monday.
The phrases 'Lo voy a pensar' and 'Déjame pensarlo' are the most common and universally understood across Latin America for everyday conversation.
While the main phrases are used, it's also common to hear 'Me lo voy a pensar' or 'Me lo pensaré.' The reflexive 'me' is often added for emphasis.
You will hear 'Dejame pensarlo' (pronounced with stress on the 'ja'). The main phrases 'Lo voy a pensar' and 'Lo pensaré' are also perfectly standard.
The recommended translation 'Lo voy a pensar' is extremely common and natural in these regions.
Pensar sobre eso. — Voy a pensar en eso / Lo voy a pensar. — In Spanish, you 'think *in*' a topic ('pensar en'), not 'about' it ('pensar sobre'). Even better for this context is using the direct object pronoun 'lo' ('it') before the verb, as in 'Lo voy a pensar,' which is the most natural-sounding option.
Pensaré lo. — Lo pensaré. — Object pronouns like 'lo' (it) must come *before* the conjugated verb in simple tenses like the future tense. The pronoun cannot be placed after.
Voy a pensar lo. — Lo voy a pensar / Voy a pensarlo. — With the 'ir a + infinitive' structure, you have two choices for placing the object pronoun: either before the conjugated verb 'voy' ('Lo voy a pensar') or attached to the end of the infinitive 'pensar' ('Voy a pensarlo'). Both are correct, but putting it in the middle is wrong.
