Η νύφη ψάχνει νυφικό, αλλά ο γαμπρός δεν έχει βρει ακόμα κοστούμι.

These are the definite articles in Greek, equivalent to the in English.

• η νύφη = the bride
• ο γαμπρός = the groom

Greek articles change for gender, number, and case. Here:

• η is the feminine singular form
• ο is the masculine singular form

So the article has to match the noun:

• νύφη is feminine
• γαμπρός is masculine

Unlike English, Greek uses articles very regularly, so learners need to pay close attention to them.

Because here they mean a wedding dress and a suit, not the wedding dress or the suit.

So:

• ψάχνει νυφικό = is looking for a wedding dress
• έχει βρει ακόμα κοστούμι = has found a suit yet

Greek often leaves the indefinite article untranslated in sentences like this. Greek does have forms for a/an:

• ένα νυφικό
• ένα κοστούμι

But after verbs like ψάχνω and βρίσκω, it is very common to leave the noun without ένα when speaking generally.

So both of these are natural, but the version without ένα is very normal:

• ψάχνει νυφικό
• ψάχνει ένα νυφικό

Because the two actions are viewed differently.

• ψάχνει = is looking / looks for
• δεν έχει βρει ακόμα = has not found yet

So:

• The bride is currently in the process of searching
• The groom has not succeeded up to now

ψάχνει is the present tense of ψάχνω.

έχει βρει is the present perfect, formed with:

• έχει = has
• βρει = past participle-like form used in the perfect

This is very similar to English:

• She is looking for...
• He has not found... yet

Greek often uses the perfect when the result up to the present moment matters.

The dictionary form is βρίσκω, meaning to find.

But Greek verbs often change stem in different tenses. For this verb:

• Present: βρίσκω = I find
• Aorist: βρήκα = I found
• Perfect: έχω βρει = I have found

So βρει is part of the perfect construction and comes from the same verb, even though it looks different.

This is something learners simply need to get used to: many common Greek verbs have a different aorist/perfect stem.

A few helpful forms:

• βρίσκω = I find
• βρίσκεις = you find
• βρίσκει = he/she/it finds
• βρήκα = I found
• έχει βρει = he/she has found

δεν is the normal word for not before verbs in statements.

So:

• έχει βρει = has found
• δεν έχει βρει = has not found

The negative word usually comes right before the conjugated verb, not before the whole phrase in the English way.

So Greek builds it like this:

• δεν
  • έχει
    • βρει
      • ακόμα

Literally:

• not
  • has
    • found
      • yet/still

That is why δεν comes before έχει, not before βρει.

Here ακόμα means yet.

So:

• δεν έχει βρει ακόμα κοστούμι = he hasn’t found a suit yet

But ακόμα can also mean still or even, depending on context.

Examples:

• Ακόμα περιμένω. = I’m still waiting.
• Δεν ήρθε ακόμα. = He/She hasn’t come yet.
• Ακόμα και αυτό... = Even that...

In this sentence, because it appears with a negative perfect verb, the most natural translation is yet.

Yes, Greek word order is more flexible than English word order.

The sentence as given is very natural:

• δεν έχει βρει ακόμα κοστούμι

But you may also hear:

• δεν έχει ακόμα βρει κοστούμι
• ακόμα δεν έχει βρει κοστούμι

These all mean roughly the same thing, though the emphasis can shift slightly.

The given version sounds neutral and natural:

• he hasn’t found a suit yet

Greek often moves adverbs like ακόμα for rhythm or emphasis, more freely than English does.

Yes, they are direct objects, so they are in the accusative case.

• The bride is looking for a wedding dress
• The groom has not found a suit

However, both νυφικό and κοστούμι are neuter singular nouns, and for many neuter nouns, the nominative and accusative forms are identical.

So the forms look the same:

• nominative: το νυφικό, το κοστούμι
• accusative: το νυφικό, το κοστούμι

That is why you do not see a visible change here.

If the objects were masculine or feminine, the accusative might look different.

No. νυφικό specifically means a bridal gown / wedding dress.

It is not the general word for dress. The general word is:

• φόρεμα = dress

So:

• νυφικό = wedding dress, bridal dress
• φόρεμα = dress in general

That makes this sentence especially natural in a wedding context:

• the bride is looking for a νυφικό
• the groom is looking for a κοστούμι

The accent marks show which syllable is stressed.

A rough pronunciation guide:

• Η νύφη = ee NEE-fee
• ψάχνει = roughly PSAHH-nee
• νυφικό = nee-fee-KO
• αλλά = ah-LA
• ο γαμπρός = o gham-BROS
• δεν έχει βρει ακόμα κοστούμι = den E-hee vree a-KO-ma ko-STOO-mi

A few sound notes:

• η / ι / υ / ει / οι often sound like ee
• ψ sounds like ps
• χ is a rough sound, like the ch in German Bach or Scottish loch
• μπ in γαμπρός is pronounced b here
• γ before α is a soft voiced sound, often approximated as gh

The stress is important in Greek, so the accents are not optional for learners.

Yes, that is possible, but it is slightly different in feel.

• δεν έχει βρει ακόμα κοστούμι = he hasn’t found a suit yet
• δεν βρήκε ακόμα κοστούμι = often also understood as he hasn’t found a suit yet, especially in everyday speech

In modern spoken Greek, the aorist is often used where English would prefer a present perfect. So both can be heard.

Still, δεν έχει βρει ακόμα makes the connection to the present moment especially clear: up to now, he has not found one.

So the version in your sentence is a very good one to learn because it matches English has not found yet quite neatly.
