"Do not think about it too much!"

Translation: Non pensarci troppo!

[gracie.db]

Why do we use ci here rather than lo or la?

[GiulioAles]

"Ci" is used in three different ways:

Adverb = there
e.g. "Vuoi andare al ristorante? Sì, ci voglio andare." = "Do you want to go to the restaurant? Yes, I want to go there."

Personal pronoun = us
e.g. "Ci piace la pizza" = "We like pizza"

Demonstrative pronoun = about/with/in/... it/this/that, or to him/her
e.g. "Pensaci" = "Think about it", "Parlaci" = "Talk to him/her"

Thank you for this explanation.
But would "pensarlo" be wrong?

[mariaelena256]

thanks for this explanation

I guess you might have typos for pensarci and parlarci. Please correct me if I am wrong.

[dwarven_hydra]

"ci" is apparently used to replace nouns used with "di", and one or two others. So, if it weren't a pronoun, it'd be "Non pensare di [x] troppo".

[GiulioAles]

Actually in this case is more the "a" preposition: "Non pensare troppo a questo".

[malcolmissimo]

The fuller version is that ci replaces a noun or phrase preceded by a, in, su, con, whereas ne replaces things preceded by di, da

I understand 'pensarci'...but why is 'Non ci pensi troppo' not correct...?

[Dan878472]

Negative command requires the infinitive

[deactivated user]

Only in the informal singular:

'Non pensarci troppo, (Roberto/ Roberta).'

[jeffrey.eggers]

I understood that "ci", when used like this, means "it" but specifically refers to something in an earlier sentence. "Lo" or "la" can mean "it" but don't necessarily have to refer to an earlier reference. So, when translating from English to Italian without any context, couldn't we use "pensarci", "pensarlo", or "pensarla"?

[mangoHero1]

I completely agree with this. By itself, to say think about it would have to be pensarlo wouldn't it? Lo is the direct object pronoun referring to the thinking? Why MUST it be ci? I get how ci can be translated as "it" as well, but I'm just trying to clarify how pensarlo is marked incorrect

[Aviva914593]

pensarci (plural) and pensarlo (singular) should both be correct

[AlanGibbon1]

Unfair! There should be context to which the "ci" is referring.
