Il volo delle otto è in ritardo.

In Italian, nouns are often used with an article where English might leave it out. Il volo means the flight.

So:

• Il volo delle otto = the eight o’clock flight
• Volo delle otto without the article can appear in some contexts, but il volo is the most normal full sentence form here.

Delle otto means of eight or more naturally the one at eight.

It is made of:

• di = of
• le = the (plural feminine)

These combine into delle.

In this sentence, il volo delle otto means the flight at eight o’clock or the eight o’clock flight.

Italian often uses an article with clock times: le otto = eight o’clock.

Because the phrase is linked to volo with di, you get:

• di + le otto → delle otto

So:

• le otto = eight o’clock
• il volo delle otto = the flight of eight o’clock / the eight o’clock flight

When telling time, Italian uses an implied feminine plural noun such as ore (hours), even when it is not stated.

So:

• Sono le otto = literally They are the eight hours
• le otto is therefore feminine plural

That is why you get delle otto rather than something like dei otto.

Normally, delle otto refers to the flight scheduled for eight o’clock.

In everyday use, it identifies the flight by its departure time. It does not usually mean around eight. If you wanted to be more exact, context would clarify whether it is departure time, boarding time, and so on, but most often it means the flight scheduled at 8:00.

The accent distinguishes è (is) from e (and).

• è = is
• e = and

So in this sentence:

• Il volo delle otto è in ritardo = The eight o’clock flight is late

The accent is essential in writing.

In ritardo is a fixed expression meaning late or delayed.

• essere in ritardo = to be late

So:

• Il volo è in ritardo = The flight is late / delayed

Italian often uses a prepositional phrase where English uses a simple adjective. You should learn in ritardo as a set phrase.

Not exactly.

• essere in ritardo = to be late / delayed
• ritardato exists, but it is not the normal way to describe a late flight in everyday Italian

For a flight, the most natural phrasing is:

• Il volo è in ritardo

You may also hear:

• Il volo ha ritardo in very technical or regional usage, but è in ritardo is the standard phrase learners should use.

This is the normal Italian word order:

• subject: Il volo delle otto
• verb: è
• complement: in ritardo

Italian is fairly flexible with word order, but this version is the most neutral and natural. You could change the order for emphasis, but this sentence is the standard way to say it.

No, that would not sound correct here.

To refer to a clock time, Italian uses the article:

• le otto = eight o’clock

So when linked with di, it becomes:

• delle otto

Therefore:

• Il volo delle otto = correct
• Il volo di otto = not correct for the eight o’clock flight

Not necessarily. Italian often leaves that unstated if the context makes it clear.

• le otto can mean 8:00 AM or 8:00 PM

If needed, Italian can specify:

• le otto di mattina = 8 in the morning
• le otto di sera = 8 in the evening

But in a sentence like this, context usually tells you which flight is meant.

Volo is pronounced roughly VOH-loh.

It takes il because volo begins with a consonant sound that normally uses il in the singular masculine:

• il volo
• il treno
• il tavolo

You use lo before certain special consonant combinations, such as:

• lo studente
• lo zaino
• lo psicologo

Since volo starts with a simple v, the correct article is il.

Yes. In English, both are natural translations depending on context.

• The flight is late is the most direct translation.
• The flight is delayed is also very common, especially in airport contexts.

Italian è in ritardo covers that idea naturally.
