DI, A, DA and IN are four of the smallest words in Italian — and four of the easiest to get wrong. Each one covers several unrelated uses, so there’s no single rule that works for all of them. Here’s each preposition broken down on its own, with the exact situations where it’s used and real examples for each.
DI is the most versatile of the four — it covers three separate uses.
1. DI for possession
Use DI when something belongs to someone. It works like the English possessive “‘s”, just reversed.
2. DI for origin, with the verb essere
To say where you’re from with the verb essere (“to be”), always use DI — never DA.
3. DI for the topic of something
Use DI to say what a book, film, or conversation is about.

| di + il | del | il libro del professore — “the professor’s book” |

| di + lo | dello | il nome dello studente — “the student’s name” |
| di + i | dei | i libri dei ragazzi — “the kids’ books” |
| di + gli | degli | il lavoro degli insegnanti — “the teachers’ work” |
| di + le | delle | le borse delle ragazze — “the girls’ bags” |
1. A for place — where you are, where you’re going
Key rule: A is always used with cities.
It’s also used with many common places: vado al parco (“I’m going to the park”), sono a casa (“I’m at home”), ci vediamo alla stazione (“see you at the station”).
2. A for time — the hour
3. A for the recipient of an action
Used with verbs like dare (to give), telefonare (to call), scrivere (to write).
A + article — the contracted forms
| A + article | Contracted form | Example |
|---|---|---|
| a + il | al | vado al museo — “I’m going to the museum” |
| a + la | alla | ci vediamo alla stazione — “see you at the station” |
| a + lo | allo | vado allo stadio — “I’m going to the stadium” |
| a + i | ai | vado ai giardini — “I’m going to the gardens” |

Take the free quiz →1. DA for origin — the starting point
Key distinction: with essere (“to be”) use DI; with movement verbs like venire (to come), arrivare (to arrive), partire (to leave), use DA.
2. DA for an action that started in the past and is still going
DA + a time period marks something that started earlier and continues now — equivalent to English “since”/”for” + present perfect.
3. DA for “at someone’s place”
When the place is expressed with a person’s name instead of a location, the preposition is always DA.
DA + article — the contracted forms
| DA + article | Contracted form | Example |
|---|---|---|
| da + il | dal | vado dal dentista — “I’m going to the dentist’s” |
| da + la | dalla | sono dalla parrucchiera — “I’m at the hairdresser’s” |
| da + lo | dallo | vengo dallo psicologo — “I’m coming from the psychologist’s” |
| da + i | dai | torno dai miei — “I’m coming back from my parents'” |
| da + gli | dagli | vengo dagli amici — “I’m coming from my friends'” |
| da + le | dalle | arrivo dalle tre — “I arrive from three o’clock” |
1. IN for place
Rule: IN is used with countries, regions, and places ending in -ia or -teca (like libreria, biblioteca).
A or IN? Some places take A (vado al parco, a scuola), others take IN (vado in piscina, in palestra) — there’s no single rule, just the most common combinations to memorize.
2. IN with means of transport
Exception: “on foot” is a piedi, not “in piedi”.
3. IN for time — months and seasons
IN + article — the contracted forms
| IN + article | Contracted form | Example |
|---|---|---|
| in + il | nel | nel parco — “in the park” |
| in + la | nella | sono nella pizzeria vicino a casa — “I’m at the pizzeria near home” |
| in + lo | nello | metto il portafoglio nello zaino — “I put my wallet in the backpack” |
| in + i | nei | nei negozi — “in the shops” |
| in + gli | negli | negli uffici — “in the offices” |
| in + le | nelle | nelle scuole — “in schools” |
| Preposition | Main uses | Key patterns | Example |
|---|---|---|---|
| DI | possession, origin, topic | è di, libro di, film di | Il libro di Luca. Sono di Napoli. |
| A | cities, time, recipient | a Roma, alle 8, a Luca | Vivo a Roma. Telefono a mia sorella. |
