"Lo vedo." "La conosco." "Li mangio." "Le leggo."
Four tiny words - lo, la, li, le - and most English speakers translate them the same way every time: "it" or "them." That's the mistake. In Italian these four words change constantly, and once you know the rule, half your sentences suddenly get shorter and more natural.
The rule in one sentence
Direct object pronouns replace the THING (or person) that receives the action directly - no preposition in between - and they must agree in gender and number with that thing, not with the subject.
| Pronoun | Replaces | Example |
|---|---|---|
| lo | masculine singular | Mangio il pane → Lo mangio. |
| la | feminine singular | Leggo la lettera → La leggo. |
| li | masculine plural | Compro i libri → Li compro. |
| le | feminine plural | Conosco le ragazze → Le conosco. |
Where does the pronoun go?
Almost always right before the verb (the opposite of English word order):
- Non lo capisco. → I don't understand it.
- La vedo domani. → I'm seeing her tomorrow.
With an infinitive, the pronoun can attach to the END of the verb instead, and the final -e of the infinitive drops:
- Devo farlo. → I have to do it. (instead of "Lo devo fare" - both are correct!)
The trap: past tense agreement
With lo, la, li, le + passato prossimo, the past participle must agree with the pronoun:
- Ho comprato la torta → L'ho comprata (not "comprato"!)
- Ho visto i film → Li ho visti
This single rule trips up learners at every level - even advanced ones. If you already read our post on passato prossimo with essere or avere, this is the natural next step: once you're comfortable choosing the auxiliary, this is the detail that makes your Italian sound truly native.

L'ho mangiata. (feminine → the participle agrees: mangiata, not mangiato)
3) "Compro i biglietti" → replace "i biglietti". Click for the answer.
Li compro. (masculine plural)
