Το πλήρωμα φτάνει αύριο.

Το is the definite article, meaning the.

It is neuter singular nominative, because πλήρωμα is a neuter singular noun and it is the subject of the sentence. In Greek, the article agrees with the noun in gender, number, and case.

So:

• το = the
• πλήρωμα = a neuter singular noun
• therefore το πλήρωμα = the crew

It is grammatically singular.

Even though a crew is made up of several people, Greek treats πλήρωμα as one collective unit, just like English crew can be singular. That is why the verb is also singular:

• το πλήρωμα φτάνει = the crew arrives

If the subject were a plural noun, the verb would also be plural.

Because the subject, το πλήρωμα, is singular.

• φτάνει = arrives / is arriving for he / she / it or a singular noun
• φτάνουν = arrive for they or a plural noun

Since πλήρωμα is singular, Greek uses φτάνει.

The dictionary form is φτάνω.

Φτάνει is the third-person singular present tense form of φτάνω, so it is the form used with:

• he
• she
• it
• or a singular noun such as το πλήρωμα

You may also see the more formal spelling φθάνω, but in everyday modern Greek φτάνω is very common.

Greek often uses the present tense for a future event when the time is already clear from context.

Here, αύριο means tomorrow, so the future meaning is obvious. Because of that, φτάνει can naturally mean arrives tomorrow or is arriving tomorrow.

English does something similar:

• The train leaves tomorrow.
• My friend comes back next week.

So Το πλήρωμα φτάνει αύριο is a very natural Greek sentence.

Because Greek does not always need θα when a future time expression already makes the meaning clear.

You can also say:

• Το πλήρωμα θα φτάσει αύριο.

That is also correct and is a more explicitly future form.

Very roughly:

• φτάνει αύριο can sound like a planned, expected, or scheduled arrival
• θα φτάσει αύριο is a straightforward future statement

In real Greek, both are possible, depending on context and style.

Αύριο is an adverb meaning tomorrow.

It tells you when the crew arrives. It does not change form here, and it does not need an article.

So the sentence breaks down like this:

• Το πλήρωμα = the crew
• φτάνει = arrives / is arriving
• αύριο = tomorrow

Yes. Greek word order is more flexible than English word order.

This sentence uses a very neutral order:

• Το πλήρωμα φτάνει αύριο.

But you could also say:

• Αύριο φτάνει το πλήρωμα.
• Φτάνει αύριο το πλήρωμα.

The basic meaning stays the same, but the emphasis changes:

• starting with αύριο highlights the time
• starting with φτάνει can highlight the action

English is usually much less flexible about this.

A simple pronunciation guide is:

to PLI-ro-ma FTA-ni AV-rio

A few helpful points:

• πλήρωμα is stressed on πλή
• φτάνει is stressed on φτά
• αύριο is stressed on αύ

Also:

• the cluster φτ at the start of φτάνει may feel unusual to English speakers, but it is completely normal in Greek
• αι in modern Greek is pronounced like e, so φτάνει sounds roughly like FTA-nee
