Il volo è già completo.

Il is the masculine singular definite article, meaning the.

So:

• il volo = the flight

Italian usually uses articles more regularly than English, so when you are talking about a specific flight, il is normal.

Yes, volo is a masculine singular noun.

You can tell because it takes:

• il → masculine singular article
• completo → masculine singular adjective form

So the grammar matches:

• il volo
• è completo

If the noun were feminine, the adjective would change too.

È is the 3rd person singular of essere (to be), meaning is.

• è = is
• e = and

The accent matters because it helps distinguish these two very common words.

So:

• Il volo è completo = The flight is full/fully booked
• Il volo e completo would be wrong

Già means already.

It shows that the flight became full earlier than expected, or that it is full now at this point.

So the sentence structure is:

• Il volo = the flight
• è = is
• già = already
• completo = full / fully booked

In Italian, adverbs like già often come after the conjugated verb.

So:

• è già completo = is already full

This is the most natural placement here.

English also does something similar:

• is already full

So the word order is actually quite close to English in this sentence.

Because completo agrees with volo, and volo is masculine singular.

Italian adjectives change form to match the noun they describe.

Examples:

• il volo è completo = masculine singular
• la sala è completa = feminine singular
• i voli sono completi = masculine plural
• le prenotazioni sono complete = feminine plural

Agreement is a very important part of Italian grammar.

It is understandable, but in everyday Italian, native speakers often say:

• Il volo è al completo.
• Il volo è pieno.

Al completo is especially common for fully booked / no seats left.

So while Il volo è già completo can be understood, many learners will also want to know that these alternatives may sound more idiomatic in real-life travel contexts.

They are similar, but the nuance can change a little.

• completo = complete / full
• al completo = fully occupied / fully booked / all places taken
• pieno = full

For flights, hotels, and events, al completo is often a very natural choice when you mean sold out or fully booked.

So:

• Il volo è già completo = understandable
• Il volo è già al completo = very natural for already fully booked
• Il volo è già pieno = also natural, more directly already full

Yes.

• Il volo è completo. = The flight is full.
• Il volo è già completo. = The flight is already full.

Adding già gives extra information about timing.

A very natural opposite is:

• Il volo non è ancora completo.

Here:

• non = not
• ancora = yet / still

So:

• già = already
• ancora = yet / still

These two words are often learned together because they contrast nicely.

A rough pronunciation guide is:

eel VOH-lo eh jah kom-PLEH-toh

A few details:

• il sounds like eel
• volo has stress on the first syllable: VOH-lo
• è sounds like eh
• già sounds like jah
• completo has stress on ple: kom-PLEH-to

The accent marks in è and già help show the correct written form, and they also point to the stressed vowel.

Yes. If you are talking about more than one flight:

• I voli sono già completi.

Changes:

• il → i
• volo → voli
• è → sono
• completo → completi

This is a good example of how several words in an Italian sentence can change together.

Because completo is functioning as an adjective, and Italian uses essere (to be) to link the subject to an adjective.

So the pattern is:

• subject + essere + adjective

Examples:

• Il volo è completo.
• La stanza è pronta.
• I posti sono liberi.

This is the same basic idea as English:

• The flight is full.
• The room is ready.
• The seats are free.
