Devo confermare la prenotazione dell’hotel prima di partire.

In Italian, the subject pronoun is often omitted because the verb ending already shows who the subject is.

• devo = I must / I have to
• The -o ending tells you it is io

So Devo confermare... is completely natural.
You could say Io devo confermare... if you want extra emphasis, such as:

• Io devo confermare, non tu. = I have to confirm, not you.

After modal verbs like dovere (must/have to), potere (can), and volere (want), Italian usually uses a second verb in the infinitive.

So:

• devo confermare = I have to confirm
• voglio partire = I want to leave
• posso entrare = I can come in

This works much like English:

• I must confirm
• I want to leave

Devo is the 1st person singular present tense of dovere.

Present tense of dovere:

• io devo
• tu devi
• lui/lei deve
• noi dobbiamo
• voi dovete
• loro devono

So in this sentence, devo means I must or I have to.

Italian uses definite articles more often than English does.

So la prenotazione literally means the reservation/booking, but in English we might simply say my booking or just the booking, depending on context.

In Italian, using the article here is completely normal:

• confermare la prenotazione
• cancellare la prenotazione
• modificare la prenotazione

Even when English might leave the article out, Italian often keeps it.

dell’ is a contraction of:

• di + l’ = dell’

Here di means of, so:

• la prenotazione dell’hotel = the hotel reservation / literally the reservation of the hotel

Italian often expresses this kind of relationship with di:

• il numero della camera = the room number
• la reception dell’hotel = the hotel reception
• il nome dell’albergo = the name of the hotel

In Italian, the h is silent, so hotel is treated as if it begins with a vowel sound.

That is why you get:

• l’hotel
• dell’hotel
• all’hotel
• nell’hotel

This is similar to how Italian uses l’ before vowel sounds:

• l’amico
• l’aeroporto
• l’hotel

Yes. Both are correct, but they can sound slightly different in tone or usage.

• hotel is very common and international
• albergo is also standard Italian and may sound a bit more traditionally Italian

So you could also say:

• Devo confermare la prenotazione dell’albergo prima di partire.

That is perfectly correct.

After prima when introducing an infinitive, Italian uses di, not da.

So the pattern is:

• prima di + infinitive

Examples:

• prima di uscire = before going out
• prima di mangiare = before eating
• prima di partire = before leaving

Using da here would be incorrect.

Because prima di is followed by an infinitive when the subject is the same as in the main clause.

In this sentence, the person who must confirm is also the person who will leave:

• Devo confermare ... prima di partire.

That means:

• I have to confirm ... before leaving

If the subject changes, Italian normally uses a full clause instead. For example:

• Devo confermare la prenotazione prima che lui parta.
• I have to confirm the reservation before he leaves.

So:

• same subject → prima di + infinitive
• different subject → often prima che + subjunctive

Usually, yes, but the exact English translation depends on context.

Partire often means:

• to leave
• to depart
• to set off

In this sentence, it most naturally means something like:

• before leaving
• before departing

Because the sentence mentions a hotel reservation, the learner might wonder whether it means leaving for the trip or leaving the hotel. The grammar itself does not specify that exactly; the surrounding context would decide.

Yes. Italian word order is flexible, though the original version is very natural.

Original:

• Devo confermare la prenotazione dell’hotel prima di partire.

Other possible orders:

• Prima di partire, devo confermare la prenotazione dell’hotel.
• La prenotazione dell’hotel devo confermarla prima di partire.
  This version is more marked or emphatic.

The original is the most neutral and straightforward.

Prenotazione can correspond to both reservation and booking in English.

Examples:

• fare una prenotazione = to make a reservation / booking
• confermare una prenotazione = to confirm a reservation / booking
• cancellare una prenotazione = to cancel a reservation / booking

So if you are thinking in English, both are reasonable translations depending on the situation and style.

The apostrophe appears because lo or la becomes l’ before a vowel sound.

The full structure is:

• di + l’hotel
• written together as dell’hotel

This is part of Italian’s normal article-preposition combinations.

A few similar examples:

• di + l’amico = dell’amico
• a + l’hotel = all’hotel
• in + l’ufficio = nell’ufficio

So the apostrophe is not optional here; it is the standard spelling.
