Prima di partire, smontiamo il letto e lo portiamo giù con attenzione.

Prima di means before when it is followed by a verb. After di, Italian normally uses the infinitive:

• prima di partire = before leaving
• prima di mangiare = before eating
• prima di dormire = before sleeping

So partire stays in its base infinitive form because it depends on di.

If you wanted to say before we leave, Italian could also use a full clause, but prima di + infinitive is very common when the subject is understood from the context.

Partire means to leave / to depart, often with the sense of setting off on a trip or going away. In this sentence, it fits naturally because the context suggests getting ready to go.

Possible alternatives exist, but they are not exactly the same:

• partire = leave, depart, set off
• andare via = go away
• uscire = go out / leave a place

So prima di partire sounds very natural for before leaving in the sense of departure.

Smontiamo comes from smontare, which can mean:

• to take apart
• to dismantle
• to disassemble

So smontiamo il letto means we take the bed apart or let’s take the bed apart, depending on context.

With furniture, smontare is the normal verb for separating it into pieces so it can be moved more easily.

It can mean both, depending on context.

The form smontiamo is grammatically the 1st person plural present indicative:

• noi smontiamo = we dismantle / we are dismantling

But in everyday Italian, the same form is also often used as an exhortation:

• smontiamo il letto = let’s dismantle the bed

That is similar to English Let’s...

The same applies to portiamo:

• lo portiamo giù = we take it downstairs or let’s take it downstairs

Without more context, both readings are possible. In a practical instruction-like sentence, English often translates it as let’s.

Italian often introduces the noun first, then replaces it with a pronoun once it has already been mentioned.

Here:

• il letto = the bed
• lo = it

So:

• smontiamo il letto = we dismantle the bed
• e lo portiamo giù = and we take it downstairs

Using lo avoids repeating il letto. This is exactly like English using it after already mentioning the bed.

In Italian, direct object pronouns usually come before a conjugated verb:

• lo portiamo = we take it
• la vedo = I see her / it
• li compro = I buy them

So lo portiamo is the normal word order.

Compare this with infinitives, where pronouns can attach to the end:

• portarlo = to take it
• smontarlo = to dismantle it

But with a conjugated verb like portiamo, the pronoun goes before it: lo portiamo.

Here giù means down or, more naturally in English, downstairs.

So portare giù means:

• to take down
• to carry downstairs

Because the object is a bed and the context is moving it, downstairs is a very natural translation.

Examples:

• porto giù le valigie = I’m taking the suitcases downstairs
• scendi giù is common in speech, though scendi already means go down

Because giù is an adverb, not a noun. It directly modifies the verb:

• portare giù = to take down
• buttare giù = to throw down / knock down
• scendere giù = to go down

Italian often uses adverbs of place this way without needing an extra preposition.

If you wanted to be more explicit, you could say something like:

• al piano di sotto = to the floor below / downstairs

But giù by itself is very natural and idiomatic.

Con attenzione means carefully or more literally with attention.

It tells you how the action is done. In English, we usually prefer the adverb carefully, but Italian often uses:

• con attenzione
• con cura
• attentamente

So these are all similar:

• lo portiamo giù con attenzione
• lo portiamo giù attentamente

The version with con attenzione sounds very natural and slightly more concrete: do it with care and attention.

Italian uses articles much more often than English. When talking about a specific countable object, Italian usually includes the definite article:

• il letto = the bed
• la porta = the door
• i libri = the books

English sometimes drops the article in certain expressions, but Italian often keeps it.

Here it is a specific bed, so il letto is exactly what you would expect.

Yes, but that would create a different structure.

For example:

• Prima di partire, dobbiamo smontare il letto e portarlo giù con attenzione.
• Prima di partire, bisogna smontare il letto e portarlo giù con attenzione.

Here portarlo means to take it downstairs, with -lo attached to the infinitive portare.

In the original sentence, the verbs are conjugated:

• smontiamo
• portiamo

So the pronoun must come before the conjugated verb:

• lo portiamo

Both structures are correct; they are just built differently.

It is very natural and usually preferred.

Prima di partire is an introductory phrase, and Italian often separates that kind of phrase with a comma:

• Prima di partire, smontiamo il letto...

The comma helps readability and marks a pause. In very short sentences, punctuation can sometimes vary, but here the comma is standard and clear.

Grammatically, it most directly attaches to the second action, lo portiamo giù.

So the most immediate reading is:

• we dismantle the bed and carry it downstairs carefully

However, in real context, the idea of being careful can easily be understood as applying to the whole process, especially because moving a dismantled bed involves care at every stage.

If the speaker wanted to make it clearer that both actions must be done carefully, they could say:

• Prima di partire, smontiamo il letto con attenzione e lo portiamo giù.

That would place con attenzione more clearly with smontiamo.
