Akşam damat ve gelin bize kahve içmeye gelecek.

Here Akşam is being used as a time expression, so it means something like this evening / tonight / in the evening, depending on context.

Turkish often uses time words without a preposition:

• Akşam geliyorum. = I’m coming tonight / in the evening.
• Sabah aradım. = I called in the morning.

If you want to be more explicitly specific, you can say Bu akşam = this evening / tonight.

Because the sentence is talking about one groom and one bride.

Turkish, like English, normally uses two singular nouns joined by ve when it means one of each:

• damat ve gelin = the groom and the bride

If you said damatlar ve gelinler, that would mean grooms and brides in the plural, so it would sound like multiple couples or groups.

Turkish does not have articles like English the and a/an.

So damat ve gelin can mean:

• the groom and the bride
• or, in another context, a groom and a bride

The exact meaning comes from context.

Turkish can use bir to mean a / one, but it is not required in many cases:

• bir damat = a groom / one groom
• damat = groom / the groom, depending on context

Bize is biz + dative ending -e, so it means to us.

With the verb gelmek (to come), Turkish usually uses the dative case for the destination:

• bize gelmek = to come to us / to our place

Compare:

• bize = to us
• bizde = at our place / with us
• bizi = us as a direct object

So:

• Bize gelecek. = He/She/They will come to us.
• Bizde kalacak. = He/She/They will stay at our place.

Because Turkish often uses verb + -meye / -maya after motion verbs like gelmek and gitmek to show purpose.

So:

• kahve içmeye gelmek = to come to drink coffee
• more naturally in English: to come over for coffee

The form breaks down like this:

• içmek = to drink (dictionary form)
• içme = verbal noun / infinitive-like form
• içmeye = to drinking / for drinking

In this pattern, the meaning is basically:

• He/She/They come in order to drink coffee

The -ye is the dative ending added to içme.

Breakdown:

• iç- = drink
• -me = verbal noun marker
• -ye = dative ending

So:

• içme
  • -ye → içmeye

The y is just a buffer consonant used because the word already ends in a vowel.

This -meye / -maya pattern is very common after motion verbs:

• yemek yemeye gitmek = to go to eat
• çay içmeye gelmek = to come to drink tea
• gezmeye çıkmak = to go out for a walk / sightseeing

Because kahve here is an indefinite, non-specific object.

In Turkish, a direct object often stays without the accusative ending when it is general or indefinite:

• kahve içmek = to drink coffee
• kitap okumak = to read a book / read books

If you said kahveyi, that usually points to a specific coffee already known in the conversation:

• kahveyi içmek = to drink the coffee / that coffee

In this sentence, they are coming for coffee in general, not for one specific identified coffee, so kahve is the natural form.

Because in Turkish, when the subject is already clearly stated, a 3rd person plural ending is often optional.

So both of these can be acceptable:

• Damat ve gelin gelecek.
• Damat ve gelin gelecekler.

The version with gelecek is very natural in everyday Turkish.
The version with gelecekler can sound a bit more explicit or formal.

This is common with plural subjects in Turkish, especially when the subject is already mentioned.

Yes. That would also be correct.

Compare:

• kahve içmeye gelecek
• kahve içmek için gelecek

Both mean roughly will come to drink coffee.

The difference is mainly style:

• -meye gelmek / gitmek is a very common, compact pattern after motion verbs
• -mek için means in order to, and works more broadly

So:

• Bize kahve içmeye gelecek. sounds very natural and idiomatic.
• Bize kahve içmek için gelecek. is also correct, but slightly less compact.

No, Turkish word order is somewhat flexible, but this sentence has a very natural order.

Current order:

• Akşam = time
• damat ve gelin = subject
• bize = destination
• kahve içmeye = purpose
• gelecek = verb

A very literal structure is:

• Tonight the groom and bride to us coffee-drink-for will come.

Turkish usually puts the main verb at the end, and elements before it can move around for emphasis.

For example, these are also possible:

• Damat ve gelin akşam bize kahve içmeye gelecek.
• Bu akşam damat ve gelin bize kahve içmeye gelecek.

The meaning stays similar, but the emphasis changes slightly.

Not always.

These words can also have family meanings:

• damat can mean groom or son-in-law
• gelin can mean bride or daughter-in-law

In this sentence, because they appear together as damat ve gelin, the most natural reading is the bride and groom (or a newly married couple).

So the exact meaning depends on context, but here the pairing strongly suggests bride and groom.
