Ο δικαιούχος λογαριασμού περιμένει.

Ο is the masculine singular definite article, meaning the.

So:

• ο δικαιούχος = the beneficiary / the account holder

It tells you that the noun is:

• masculine
• singular
• in the nominative case here, because it is the subject of the sentence

Δικαιούχος is a noun meaning something like:

• beneficiary
• person entitled to something
• in banking or official language, often account holder

Even though the word comes from the idea of having a right or entitlement, in this sentence it clearly refers to a person.

It is also a fairly formal/official word, so this sentence sounds more administrative or bureaucratic than casual everyday speech.

Λογαριασμού is the genitive singular form of λογαριασμός (account, bill, etc.).

So the basic form is:

• ο λογαριασμός = the account

But in this sentence it becomes:

• λογαριασμού = of an account / of the account

The ending changes because Greek uses cases. Here the genitive shows a relationship, roughly like English of.

So:

• δικαιούχος λογαριασμού = literally holder/beneficiary of account

In natural English, that becomes account holder.

Good question. In Greek, when one noun is used to define another, the second noun in the genitive often appears without an article, especially in formal or set expressions.

So:

• δικαιούχος λογαριασμού = account holder
• literally: holder of account

This is common in official, legal, or banking language.

If you said:

• ο δικαιούχος του λογαριασμού

that would more specifically mean:

• the holder/beneficiary of the account

So the version without του can sound a bit more like a label or category, while the version with του points more clearly to a specific account.

Yes, functionally it works a lot like an English compound such as account holder.

Greek often expresses this idea with:

• a main noun
• plus another noun in the genitive

So instead of putting nouns directly side by side the way English does, Greek often uses:

• δικαιούχος λογαριασμού
• literally holder of account
• naturally account holder

This is a very common Greek pattern.

The subject is the whole noun phrase:

• Ο δικαιούχος λογαριασμού

The main noun in that phrase is δικαιούχος, and λογαριασμού adds extra information about what kind of holder/beneficiary this is.

So the structure is:

• Ο δικαιούχος λογαριασμού = subject
• περιμένει = verb

Περιμένει is the present tense, third person singular form of περιμένω (to wait).

So it means:

• he/she/it waits
• or more naturally in many contexts, is waiting

Because Greek often does not need a separate subject pronoun, the ending -ει already tells you the subject is:

• he
• she
• or it

In this sentence, the noun phrase gives the subject explicitly:

• Ο δικαιούχος λογαριασμού περιμένει = The account holder is waiting

Because Greek does not form the present progressive in the same way English does.

English distinguishes between:

• waits
• is waiting

Greek present tense often covers both ideas, depending on context.

So:

• περιμένει can mean waits or is waiting

In most everyday contexts, English will often translate it as is waiting.

Yes. Greek word order is more flexible than English word order because the endings help show grammatical roles.

The neutral order here is:

• Ο δικαιούχος λογαριασμού περιμένει.

But you could also see:

• Περιμένει ο δικαιούχος λογαριασμού.

That might put a bit more focus on the action waiting.

Even so, the original order is the most straightforward and neutral for a learner.

A simple pronunciation guide is:

• O thee-keh-OO-hos lo-ga-rya-SMOO pe-ri-ME-ni

A few helpful notes:

• δικαιούχος has the stress on -ού-
• λογαριασμού has the stress on the last syllable -μού
• περιμένει has the stress on -μέ-

Also:

• αι is pronounced like e
• ου is pronounced like oo
• γ before front vowels can sound softer than English g

It is grammatical and understandable, but it sounds somewhat formal or administrative, especially because of δικαιούχος λογαριασμού.

In ordinary everyday conversation, people might use simpler wording depending on context. But in banking, official forms, notices, or formal descriptions, this kind of phrasing is very natural.

So it is a good example of formal practical Greek.
