Ο υπάλληλος είπε ότι χωρίς σωστό γραμματόσημο το δέμα δεν φτάνει ποτέ στον παραλήπτη.

Υπάλληλος means employee / clerk / staff member, and the noun itself can refer to either a man or a woman.

• ο υπάλληλος = the male employee / clerk
• η υπάλληλος = the female employee / clerk

So here, ο shows that the speaker is referring to a man.

Also, Greek uses the definite article much more often than English, so ο υπάλληλος is completely normal where English might simply say the clerk or the employee.

Είπε is the aorist form of λέω (to say / to tell).

So:

• λέω = I say / I am saying
• είπα = I said
• είπε = he/she/it said

This is an irregular verb, so the past form does not look very much like the present stem λέ-.

In this sentence:

• Ο υπάλληλος είπε... = The clerk said...

Ότι introduces a reported statement, so here it means that.

• είπε ότι... = said that...

It connects the main clause to what was said.

A very common alternative in everyday Greek is πως:

• Ο υπάλληλος είπε ότι...
• Ο υπάλληλος είπε πως...

Both are natural here.

In Greek, a comma is usually not placed before ότι when it introduces a normal object clause after a verb like λέω, νομίζω, ξέρω, etc.

So this is standard:

• Ο υπάλληλος είπε ότι...

A comma might appear only if the writer wants to mark a special pause or structure, but normally you do not use one here.

Because the phrase means without a proper/correct stamp in a general, indefinite sense.

• χωρίς σωστό γραμματόσημο = without a proper stamp

Greek often omits the article after χωρίς when speaking generally.

Compare:

• χωρίς σωστό γραμματόσημο = without a proper stamp, without any proper stamp
• χωρίς το σωστό γραμματόσημο = without the correct/proper stamp, with a more specific sense

So the version in the sentence sounds like a general rule.

Because γραμματόσημο is a neuter singular noun, and adjectives must agree with the noun they describe.

Here the noun is:

• το γραμματόσημο = the stamp

So the adjective must also be neuter singular:

• σωστό γραμματόσημο = proper/correct stamp

Agreement patterns:

• σωστός = masculine
• σωστή = feminine
• σωστό = neuter

Because the two noun phrases are functioning differently.

το δέμα

This refers to the parcel/package being discussed, so Greek naturally uses the article.

σωστό γραμματόσημο

This is an indefinite, general condition: without a proper stamp.

So Greek is making a distinction between:

• the specific parcel in the situation → το δέμα
• a nonspecific proper stamp → σωστό γραμματόσημο

Greek uses articles more often than English, but it still leaves them out in general/indefinite expressions like this one.

In standard Greek, δεν ... ποτέ means never.

So:

• δεν φτάνει ποτέ = it never arrives / it never reaches

This is a common Greek pattern:

• δεν = not
• ποτέ = ever / never, depending on the context

With negation, ποτέ gives the meaning never.

Examples:

• Δεν πάω ποτέ εκεί. = I never go there.
• Δεν τον βλέπω ποτέ. = I never see him.

Without δεν, ποτέ often means ever in questions or certain other contexts:

• Έχεις πάει ποτέ εκεί; = Have you ever been there?

Because Greek does not automatically shift the tense backward in reported speech the way English sometimes does.

Here, the clerk said something that is presented as a general fact or rule:

• χωρίς σωστό γραμματόσημο το δέμα δεν φτάνει ποτέ...
• without a proper stamp, the parcel never reaches...

So the present tense φτάνει is very natural, because the statement is still true as a general principle.

In other words, Greek is closer to:

• He said that without a proper stamp, the package never arrives...

rather than forcing a past form just because είπε is past.

Yes. Φτάνει is the 3rd person singular present of φτάνω (to arrive / reach).

So:

• φτάνω = I arrive / reach
• φτάνεις = you arrive
• φτάνει = he/she/it arrives

In this sentence, the subject is το δέμα, which is singular neuter, so φτάνει is the correct form.

Depending on context, φτάνω can mean:

• arrive
• reach
• get to

Here reach is the best fit because of στον παραλήπτη.

Στον is a contraction of:

• σε + τον = στον

Here σε means to / at / in, and τον is the masculine singular article in the accusative.

So:

• στον παραλήπτη = to the recipient

This contraction is extremely common in Greek:

• σε τον → στον
• σε τη(ν) → στη(ν)
• σε το → στο

Because it is the accusative singular form of παραλήπτης (recipient), and it follows the preposition σε.

The basic forms are:

• ο παραλήπτης = the recipient (nominative)
• τον παραλήπτη = the recipient (accusative)

After σε, Greek usually uses the accusative:

• στον παραλήπτη = to the recipient

This is why you do not see παραλήπτης here.

Greek word order is more flexible than English, because endings and articles show the grammatical roles more clearly.

The original sentence is very natural:

• Ο υπάλληλος είπε ότι χωρίς σωστό γραμματόσημο το δέμα δεν φτάνει ποτέ στον παραλήπτη.

But other orders are possible, depending on emphasis. For example:

• Ο υπάλληλος είπε ότι το δέμα χωρίς σωστό γραμματόσημο δεν φτάνει ποτέ στον παραλήπτη.

This puts το δέμα a little earlier and may sound slightly more focused on the package itself.

So the order can move, but the original version is smooth and idiomatic.

Yes, παραλήπτης is a real and common word, especially in postal, delivery, office, and official contexts.

It means recipient / addressee / receiver.

So in a sentence about mail or packages, στον παραλήπτη is completely natural. In less formal everyday speech, people might sometimes say something more like:

• σε αυτόν που το περιμένει = to the person waiting for it

But for parcels, letters, shipping, or post office language, παραλήπτης is exactly the right word.
