When English speakers want to name an object based on its purpose, they usually smash two words together. You sleep in a bedroom, you protect your eyes with sunglasses, and you brush your teeth with a toothbrush. Italian approaches this differently.
Instead of placing two nouns side by side, Italian uses the preposition da to connect the main item with its intended use or purpose. If you translate these combinations literally, you get phrases like room for bed, glasses for sun, and brush for teeth. This is a very common pattern that will help you learn and remember dozens of everyday vocabulary words.

Rooms and household items
Many rooms in a house get their Italian names from their primary function. A camera da letto or stanza da letto is literally a room for bed. A sala da pranzo is a room for dining.
I bambini dormono nella camera da letto.
(The children sleep in the bedroom.)
La cena è servita nella sala da pranzo.
(Dinner is served in the dining room.)
This pattern also applies to many household items and appliances. A spazzolino da denti is a brush for teeth, a ferro da stiro is an iron for ironing, and a guanto da forno is a glove for the oven.
Devo comprare uno spazzolino da denti nuovo.
(I need to buy a new toothbrush.)
Non toccare la teglia senza il guanto da forno.
(Do not touch the baking tray without the oven mitt.)
Clothing and accessories
When clothing is designed for a specific activity, da links the garment to its purpose. A costume da bagno is a suit for bathing, and occhiali da sole are glasses for the sun.
Ho dimenticato i miei occhiali da sole in macchina.
(I forgot my sunglasses in the car.)
In piscina è obbligatorio indossare la cuffia da nuoto.
(At the pool it is mandatory to wear a swimming cap.)
La sarta sta cucendo il suo abito da sposa.
(The tailor is sewing her wedding dress.)
Sports, hobbies, and machines
You will see this construction constantly when talking about sports equipment and machinery. A macchina da scrivere is a machine for writing, a macchina da caffè is for making coffee, and a campo da tennis is a court for tennis.
Ieri sera abbiamo giocato a un gioco da tavolo molto divertente.
(Last night we played a very fun board game.)
Ha venduto la sua vecchia macchina da scrivere.
(He sold his old typewriter.)
Il campo da tennis è occupato fino a domani.
(The tennis court is occupied until tomorrow.)
Watch out: Purpose vs. Contents
While da tells you what an object is designed for, it does not tell you what is currently inside it. A classic mistake is confusing the purpose of a container with its contents.
If you want to talk about the physical object designed to hold tea, you use da to express its purpose, as in tazza da tè. If you want to talk about a cup filled with tea, you use the preposition di, meaning of, to express its contents, as in tazza di tè. The same logic applies to spoons.
Aggiungi un cucchiaino da tè di zucchero alla ricetta.
(Add one teaspoon of sugar to the recipe.)
Lei ha bevuto una tazza di tè con le sue amiche.
(She drank a cup of tea with her friends.)
Summary
To talk about the specific purpose of an object, Italian links the item and its function using the preposition da. While English just puts two nouns together, Italian uses the formula: item + da + purpose.
