Ci and Ne  are two additional pronouns (or pronominal particles) that take the place of a noun. These pronouns have a variety of uses, some of which are idiomatic or particular to the Italian language and do not have a literal translation to English.  This section will introduce a common use of each pronoun.
Note that there are other uses of both CI and NE, but we will cover those in another lesson!
Like pronomi diretti and pronomi indiretti, both ci and ne precede the verb in a sentence.

CI
We’ve already encountered ci  in c’è/ci sono and as a direct, indirect, and reflexive pronoun. 
One other use of ci  is to indicate a place. It often substitutes qui (here) or lì (there).

Esempi:                         

Vado a Roma domani. 
I'm going to Rome tomorrow. ​

  Ci vado domani.
​  I'm going (there) tomorrow.

Marco has a good life in this city.   ​

Marco ci vive bene.
Marco has a good life here. 
 (Marco lives well in this city.)   ​

Con chi sei andato in Inghilterra?
Who did you go to England with? ​

 Con chi ci sei andato?
​ Who did you go (there) with?

---

- Sei già andato al supermercato?
- No, ci vado adesso. 
- Have you already gone to the supermarket?
- No, I’m going (there) now.

---

- Vi piace il cinema?
- Sì, ma non ci andiamo spesso. 
​- Do you (pl.) like the cinema?
- Yes, but we don’t go (there) often.

NE
Ne indicates a part of a whole, a quantity, or “not any”. It often translates as “of it” or “of them” (“…some of it”; “…two of them”)

Esempi:

Prendo quattro caramelle.
I'll take four candies. ​

Ne prendo quattro.
​I'll take four (of them).

---

Vuoi un po’ di vino? 
Do you want some wine? ​

Ne vuoi un po’?
​Do you want some (of it)?

---

- Quante pere vuole?
​- How many pears do you want?

- Me ne dia cinque, per favore.
​- Give me five of them, please.

---

Non voglio il vino. 
I don't want wine.

Non ne voglio.
​I don't want (any of) it.

---

- Quanti anni ha Luigi?
- How old is Luigi? 
​(lit. how many years does Luigi have?)

- Ne fa venti la settimana prossima
- He’ll be 20 next week.
​(lit. he’ll make 20 of them…)

---

- Questo pane va bene?
​ - Is this bread fine?

- Ne vorrei uno più piccolo.
​- I would like a smaller one (of them).

NOTA BENE!

When using NE with compound tenses like Passato Prossimo it acts like a pronome diretto - the past participle must agree in number and gender.

Esempi:

 - Quante caramelle hai mangiato?
​ - How many candies did you eat?

- Ne ho mangiate solo tre. 
​- I only ate three of them.
​

- Hai molte valigie? 
​- Do you have many suitcases?

- Ne ho portata solo una*.
- I only brought one (of them).  

*Notice that although the question mentions plural suitcases, the response is “only one” (valigia) so it agrees accordingly.
