Το πλήρωμα είναι έτοιμο.

A careful pronunciation is:

to PLEE-ro-ma EE-ne E-ti-mo

More exactly, in IPA:

/to ˈpliroma ˈine ˈetimo/

A few useful notes:

• πλήρωμα is stressed on the first syllable: ΠΛΗ-ρω-μα
• είναι is usually pronounced EE-ne in normal modern speech
• έτοιμο is stressed on έ: E-ti-mo

The accent marks in Greek show you which syllable is stressed.

το is the definite article, meaning the.

In this sentence, it matches πλήρωμα because both are:

• neuter
• singular
• nominative

So το πλήρωμα means the crew.

Greek uses the definite article very often, and in a normal sentence like this, you would usually keep it.

πλήρωμα is neuter singular.

This is important because Greek nouns have grammatical gender, and other words around them must agree with them. Even though a crew is made up of people, the noun itself is grammatically neuter.

A helpful pattern: many Greek nouns ending in -μα are neuter, such as:

• όνομα = name
• γράμμα = letter
• πρόβλημα = problem
• πλήρωμα = crew

Because the adjective has to agree with the noun.

The basic forms are:

• έτοιμος = masculine
• έτοιμη = feminine
• έτοιμο = neuter

Since πλήρωμα is neuter singular, the correct form is έτοιμο.

So:

• Ο άντρας είναι έτοιμος = The man is ready
• Η γυναίκα είναι έτοιμη = The woman is ready
• Το πλήρωμα είναι έτοιμο = The crew is ready

είναι is the present-tense form of είμαι, which means to be.

Here, είναι means is.

One useful thing to know is that είναι can also mean are in the third person, so the subject tells you whether it is singular or plural.

Examples:

• Το πλήρωμα είναι έτοιμο = The crew is ready
• Οι επιβάτες είναι έτοιμοι = The passengers are ready

Because Greek usually does not need an extra subject pronoun when the subject is already clear.

In this sentence, the subject is already stated:

το πλήρωμα

So there is no need to add it.

English says:

• The crew is ready

Greek says:

• Το πλήρωμα είναι έτοιμο

Adding a pronoun like αυτό would usually sound unnecessary here.

Because πλήρωμα is a singular collective noun.

So in Greek, it takes:

• a singular verb: είναι
• a singular adjective: έτοιμο

This is similar to English the crew is ready, where crew is grammatically singular.

If you want to talk about the individual people, Greek would normally use a different expression, for example:

• Τα μέλη του πληρώματος είναι έτοιμα = The members of the crew are ready

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

The most neutral version is:

Το πλήρωμα είναι έτοιμο

But you may also hear:

• Έτοιμο είναι το πλήρωμα
  This puts more emphasis on ready

• Είναι έτοιμο το πλήρωμα
  This can sound a bit like an announcement or a check

So the original sentence is the most straightforward, neutral way to say it.

το πλήρωμα is in the nominative, because it is the subject of the sentence.

έτοιμο is a predicate adjective after είναι, and it agrees with the subject in:

• gender
• number
• case

So the structure is:

• το = neuter singular nominative article
• πλήρωμα = neuter singular nominative noun
• είναι = verb
• έτοιμο = neuter singular predicate adjective

In normal everyday Greek, that would usually sound unnatural.

Greek generally wants the article here:

Το πλήρωμα είναι έτοιμο

Leaving out the article might happen only in very special styles, such as:

• headlines
• notes
• very telegraphic language

For a learner, the safe and natural choice is to keep το.
