Μετά το διαζύγιο έμειναν φίλοι.

In modern Greek, μετά meaning after normally takes the accusative case, so you say:

μετά το διαζύγιο = after the divorce

Older Greek used μετά with the genitive in some meanings, and you may occasionally notice that in very formal or older texts, but in everyday modern Greek, μετά + accusative is the normal pattern for after.

So:

• μετά το μάθημα = after the lesson
• μετά τη δουλειά = after work
• μετά το διαζύγιο = after the divorce

Το διαζύγιο is in the accusative singular.

That is because it follows the preposition μετά in the sense of after, and in modern Greek that preposition takes the accusative.

The dictionary form of the noun is:

• το διαζύγιο = the divorce

For this noun, the nominative and accusative singular look the same, so you do not see a form change here. But grammatically, in this sentence it is accusative because of μετά.

Έμειναν is the aorist form of the verb μένω, which basically means stay, remain, or live depending on context.

Here it means:

• they remained
• they stayed

So έμειναν φίλοι means they remained friends or they stayed friends.

Grammatically, έμειναν is:

• 3rd person plural
• aorist
• active voice

So the verb ending itself tells you the subject is they, even though Greek does not need to say they explicitly.

Greek often omits subject pronouns because the verb ending already shows who is doing the action.

In έμειναν, the ending -αν tells you it is they.

So the sentence naturally means:

• They remained friends after the divorce.

Greek does this all the time:

• πήγα = I went
• πήγες = you went
• πήγαν / πήγανε = they went

You only add the pronoun if you want emphasis or contrast.

Because φίλοι here is not the direct object of the verb. It is a predicate noun (or predicate complement): it describes what they remained.

Think of it like English:

• They remained friends.

In English, friends is not an object either; it describes the subject.

So Greek uses the nominative plural:

• φίλοι = friends

If it were a direct object, you would expect accusative, but that is not what is happening here. The structure is:

• έμειναν φίλοι = they remained friends

In this sentence, φίλοι is most naturally understood as friends, not just friendly.

That is because φίλος can be:

• a noun: friend
• sometimes an adjective in certain contexts, but much less likely here

With έμειναν φίλοι, the normal meaning is:

• they stayed friends
• they remained on friendly terms

So even though English may sometimes rephrase it, the Greek strongly points to the noun sense friends.

Yes, very common and natural.

Greek often uses μένω in expressions where English uses remain or stay:

• έμειναν φίλοι = they stayed friends
• έμεινε μόνος = he remained alone
• έμεινα άφωνος = I was left speechless / I remained speechless

So this sentence sounds completely natural in everyday Greek.

Yes. Παρέμειναν φίλοι is also correct and means almost the same thing: they remained friends.

The difference is mainly one of style and tone:

• έμειναν φίλοι = very natural, everyday
• παρέμειναν φίλοι = a bit more formal or more explicitly remained

Both are correct, but έμειναν φίλοι is especially common in ordinary speech.

Yes, Greek word order is fairly flexible.

This sentence starts with Μετά το διαζύγιο to set the time frame first:

• After the divorce, they remained friends.

That is very natural.

You could also say:

• Έμειναν φίλοι μετά το διαζύγιο.

This has the same basic meaning. The difference is mainly emphasis and flow, not grammar.

Greek often moves time expressions around more freely than English.

The dictionary forms are:

• μετά = after
• το διαζύγιο = the divorce
• μένω = stay, remain, live
• φίλος = friend

The sentence uses:

• μετά
  • accusative
• το διαζύγιο as the noun after the preposition
• έμειναν as the aorist plural of μένω
• φίλοι as nominative plural

So this is a good sentence for seeing how dictionary forms change in real use.

A simple pronunciation guide would be:

Me-TA to thia-ZY-ghio E-mi-nan FI-li

A few notes:

• Μετά has the stress on the second syllable: με-ΤΑ
• διαζύγιο has the stress on ΖΥ
• Greek γ before ι sounds soft, somewhat like a y sound blended with a light g
• φίλοι is stressed on ΦΙ

A more approximate English-style guide is:

meh-TA to thee-ah-ZEE-yio EH-mee-nan FEE-lee

Exact pronunciation depends on accent and how precise you want to be, but this should help you say it recognizably.

Yes, that is exactly the usual implication.

Μετά το διαζύγιο έμειναν φίλοι does not just give a neutral fact. It usually suggests something a little noteworthy or positive: although they got divorced, they continued to have a good relationship.

So the sentence often carries the idea:

• They divorced, but they stayed on good terms.

That nuance comes naturally from έμειναν φίλοι.
