An appositive is a noun phrase placed next to another noun to define or describe it. When you describe historical landmarks or cities in English, you almost always use an article: "Rome, the capital of Italy," or "Paris, an ancient metropolis."
In Italian, when an appositive directly follows a proper noun (like a city name), the article is omitted.
| Rome, the capital of Italy, changes year after year. | Roma, capitale d'Italia, cambia anno dopo anno. |
| Rome, the symbol of the ancient empire, is full of ruins. | Roma, simbolo dell'antico impero, è piena di rovine. |
This mandatory omission applies whether the English equivalent uses a definite article ("the") or an indefinite article ("a/an").
| Paris, an ancient metropolis, is full of culture. | Parigi, antica metropoli, è piena di cultura. |
Describing Cities
You will often use nouns like capoluogo (regional capital), sede (seat/venue), or crocevia (crossroads) to describe cities. Although you learn these words with their articles, remember to drop them when they follow a city's name as an appositive.
| Naples, the regional capital of the south, is very beautiful but I haven't been there for years. | Napoli, capoluogo del sud, è bellissima ma non ci vado da anni. |
| Venice, the seat of the exhibition, is a unique city. | Venezia, sede della mostra, è una città unica. |
| Naples, a crossroads of cultures, is a lively city. | Napoli, crocevia di culture, è una città vivace. |
Multiple Appositives
If you string together multiple descriptions with e (and), drop the article for every noun phrase in the list.
| Venice, the tourist attraction and the hub of art, is famous. | Venezia, attrazione turistica e fulcro dell'arte, è famosa. |
