Είχες να δεις την κόρη τους από πέρσι, έτσι δεν είναι; Τώρα μοιάζει πιο μεγάλη και φέρεται πιο ήρεμα.

In this sentence, είχες να δεις means something like you hadn’t seen or it had been since you last saw.

This is a very common Greek pattern:

έχω / είχα + να + verb

It often expresses that a certain amount of time has passed since someone last did something.

So:

• Έχω να τη δω από πέρσι = I haven’t seen her since last year
• Είχες να δεις την κόρη τους από πέρσι = You hadn’t seen their daughter since last year

It does not literally mean you had to see here, even though έχω να... can sometimes mean I have to... in other contexts. The time phrase από πέρσι makes the haven’t done since... meaning clear.

After να, Greek uses the subjunctive, not the ordinary indicative form.

So:

• βλέπεις = you see / you are seeing
• να δεις = to see / that you see

Here δεις is the aorist subjunctive of βλέπω. Greek often uses the aorist subjunctive when talking about a single completed event, such as seeing someone.

So είχες να δεις is the natural form for you hadn’t seen.

Because κόρη is the direct object of δεις.

You are not saying their daughter saw...
You are saying you saw their daughter.

So Greek uses the accusative:

• η κόρη = the daughter (subject form, nominative)
• την κόρη = the daughter (object form, accusative)

That is why the sentence has την κόρη τους.

Here τους means their.

So:

• η κόρη τους = their daughter
• την κόρη τους = their daughter in the accusative

Be careful: τους can also mean them in other sentences, depending on grammar and position. But here, because it follows a noun, it is the possessive pronoun their.

Από does usually mean from, but with time expressions it often corresponds to English since.

So:

• από πέρσι = since last year
• από χθες = since yesterday
• από το πρωί = since the morning / since this morning

So in this sentence, Είχες να δεις την κόρη τους από πέρσι means You hadn’t seen their daughter since last year.

It is a conversational tag, similar to:

• isn’t that right?
• isn’t it?
• right?

Literally, δεν είναι; means isn’t it? and έτσι adds the sense of so / like that / that’s the case.

So the whole phrase is a natural way to check agreement:

• Είχες να δεις την κόρη τους από πέρσι, έτσι δεν είναι;
  = You hadn’t seen their daughter since last year, had you?

No. In Greek, the semicolon (;) is used as a question mark.

So:

• Greek ; = English ?

That means:

έτσι δεν είναι;
is a question, even though it looks odd to English speakers.

Also, Greek uses the raised dot · where English often uses a colon or semicolon.

The subject is understood from context: it is their daughter.

Greek often drops subject pronouns when they are clear from the verb or the situation. This is very normal.

So after mentioning την κόρη τους, Greek does not need to say αυτή (she). The meaning is simply:

• Τώρα μοιάζει πιο μεγάλη = Now she looks older
• και φέρεται πιο ήρεμα = and she behaves more calmly

Both are possible.

Greek has two common ways to make a comparative:

• πιο + adjective
• a synthetic comparative form, such as μεγαλύτερη

So these are both natural:

• μοιάζει πιο μεγάλη
• μοιάζει μεγαλύτερη

They both mean she looks older / bigger. In everyday speech, πιο + adjective is extremely common and often feels very straightforward.

Here μεγάλη literally means big, but when talking about a child, looks bigger often naturally means looks older.

Because the two words are doing different jobs.

1. μοιάζει πιο μεγάλη

Here μοιάζει is like a linking verb: looks/seems.
So μεγάλη describes the subject, the daughter.

That means it must agree with her:

• feminine singular: μεγάλη

2. φέρεται πιο ήρεμα

Here ήρεμα describes how she behaves.
So it is an adverb, not an adjective.

• ήρεμη = calm (feminine adjective)
• ήρεμα = calmly (adverb)

So:

• She looks older → adjective
• She behaves more calmly → adverb

Here μοιάζει means looks, seems, or appears.

So:

• Τώρα μοιάζει πιο μεγάλη = Now she looks older / bigger

The verb μοιάζω can also mean resemble:

• Μοιάζει στη μητέρα της = She resembles her mother

So the exact meaning depends on the structure. In your sentence, it means seems/looks.

Φέρεται comes from φέρομαι, which often means behave or conduct oneself.

Although it looks like a passive form, many Greek verbs use these middle/passive endings with an active meaning in English.

So:

• φέρεται καλά = he/she behaves well
• φέρεται άσχημα = he/she behaves badly
• φέρεται πιο ήρεμα = he/she behaves more calmly

A very close English translation here is acts more calmly or behaves more calmly.

Because the sentence contrasts before and now.

• Είχες να δεις... από πέρσι refers to the earlier situation: you had not seen her since last year.
• Τώρα μοιάζει... και φέρεται... describes her current appearance and behavior.

So the shift in tense is exactly what English would do too:

• You hadn’t seen their daughter since last year, had you?
• Now she looks older and behaves more calmly.

No, not in this context.

That would be a misunderstanding of είχες να δεις.

As mentioned above, έχω / είχα να + verb can sometimes mean have to in certain contexts, but here the phrase από πέρσι makes it clear that the meaning is about time since the last occurrence.

So the correct sense is:

• You hadn’t seen their daughter since last year

not

• You had to see their daughter since last year
