Ο εκκαθαριστικός λογαριασμός δείχνει το πάγιο και είναι πληρωτέος.

Ο is the masculine singular definite article, meaning the.

Here it goes with εκκαθαριστικός λογαριασμός:

• Ο = the
• εκκαθαριστικός λογαριασμός = settlement/final bill

It is in the nominative masculine singular because it marks the subject of the sentence.

Because εκκαθαριστικός is an adjective describing λογαριασμός, and in Greek adjectives must agree with the noun they describe in:

• gender
• number
• case

So:

• λογαριασμός = masculine singular nominative
• εκκαθαριστικός = masculine singular nominative

That is why both have masculine singular endings.

This is a set phrase often used for bills and utilities. It usually means a settlement bill, final bill, or adjusted bill.

The adjective εκκαθαριστικός comes from the idea of settling/clearing up accounts. In practical usage, it often refers to the bill that shows the final calculation after previous estimates or advance payments.

So even though λογαριασμός can mean account or bill, in this phrase it is best understood as bill.

Greek λογαριασμός has several related meanings, including:

• account
• calculation
• bill

The exact meaning depends on context. In utility, phone, electricity, or other payment contexts, λογαριασμός very often means bill.

So in this sentence, a learner should understand it as a bill/invoice statement, not as a bank account.

δείχνει is the 3rd person singular present tense of δείχνω, meaning to show.

So:

• δείχνω = I show
• δείχνεις = you show
• δείχνει = he/she/it shows

Here the subject is Ο εκκαθαριστικός λογαριασμός, so Greek uses the 3rd person singular:

• Ο εκκαθαριστικός λογαριασμός δείχνει...
• The settlement bill shows...

Greek normally does not need a separate subject pronoun like it, because the verb ending already tells you the person and number.

Because it is the direct object of δείχνει.

The structure is:

• Ο εκκαθαριστικός λογαριασμός = subject
• δείχνει = verb
• το πάγιο = object

So Greek uses the accusative for το πάγιο.

You can see this in the article:

• το = nominative or accusative neuter singular
• here it is functioning as accusative, because it is what the bill shows

In billing language, πάγιο usually means the fixed charge, standing charge, or basic recurring fee.

It does not mean something like stable here, even though the adjective πάγιος can more generally mean fixed or constant.

In this sentence, το πάγιο is being used almost like a noun: the fixed charge.

This is very common in Greek: an adjective can be used by itself when the noun is understood from context.

πληρωτέος is an adjective meaning payable or due to be paid.

So:

• είναι πληρωτέος = is payable

This is a formal or administrative style of expression, which fits the context of bills and documents.

The adjective πληρωτέος agrees with λογαριασμός:

• λογαριασμός = masculine singular
• πληρωτέος = masculine singular

If the noun were feminine or neuter, the form would change accordingly.

Because it describes λογαριασμός, which is masculine.

Greek adjectives must agree with the noun they describe, even when they come after είναι.

So here:

• ο λογαριασμός = masculine singular
• πληρωτέος = masculine singular

Compare the same adjective with other genders:

• η δόση είναι πληρωτέα = the installment is payable
• το ποσό είναι πληρωτέο = the amount is payable

Because Greek, like English, often avoids repeating the subject when it is clearly the same.

So:

• Ο εκκαθαριστικός λογαριασμός δείχνει το πάγιο και είναι πληρωτέος.

means:

• The settlement bill shows the fixed charge and is payable.

The subject of both verbs is still Ο εκκαθαριστικός λογαριασμός.

Greek does not need to repeat ο εκκαθαριστικός λογαριασμός before είναι, because the meaning is already clear.

Not completely. Greek word order is more flexible than English, because case endings and articles help show each word’s role.

The given order is natural and neutral:

• Ο εκκαθαριστικός λογαριασμός δείχνει το πάγιο και είναι πληρωτέος.

But Greek could rearrange parts for emphasis. For example, moving το πάγιο earlier could emphasize the fixed charge.

Even so, the original sentence sounds like standard informational wording, especially in administrative or billing language.

It sounds fairly formal or administrative, especially because of words like:

• εκκαθαριστικός
• πληρωτέος

A Greek speaker might use simpler wording in everyday conversation, but on documents, invoices, statements, or official notices, this kind of phrasing is very normal.

So a learner should recognize that this is the kind of Greek often found in:

• bills
• bank statements
• utility notices
• official paperwork
