Toplantı uzayınca biraz kraker yedik, sonra çay içtik.

Uzayınca comes from the verb uzamak, which literally means to get longer / to be extended.

Here it is made of:

• uza- / uza- = verb stem
• -yınca = a suffix meaning when, once, or sometimes since/because

So:

• uzamak = to get longer, to run long
• uzayınca = when it ran long, once it got extended, or since it went on too long

In this sentence, Toplantı uzayınca... means something like:

• When the meeting ran long...
• Since the meeting dragged on...

The exact nuance depends on context.

The Turkish -ınca / -ince form can connect two events in a way that English might translate differently depending on context.

It can mean:

• when
• once
• after
• sometimes since / because

In this sentence:

• Toplantı uzayınca biraz kraker yedik
  could mean
  When the meeting ran long, we ate some crackers

  but it also naturally suggests a reason:

• Since the meeting was dragging on, we ate some crackers

Turkish often leaves that distinction slightly flexible, and context tells you which reading is most natural.

Here toplantı is the subject of the first clause, so it stays in its basic dictionary form.

• toplantı = meeting

In Toplantı uzayınca, the meeting is the thing that ran long, so it is the subject of uzayınca.

Because it is the subject, it does not need an accusative, dative, or other case ending here.

In Turkish, the accusative is usually used for specific/definite direct objects.

Here:

• biraz kraker yedik = we ate some crackers
• çay içtik = we drank tea / some tea

These are indefinite, non-specific objects, so Turkish commonly leaves them without the accusative.

Compare:

• Biraz kraker yedik = We ate some crackers.
• Krakerleri yedik = We ate the crackers.
  (specific crackers)

And:

• Çay içtik = We drank tea.
• Çayı içtik = We drank the tea.
  (a specific tea, or all of it, depending on context)

After quantity words like biraz (a little / some), Turkish often uses the noun in its bare singular form, even when English would use a plural.

So:

• biraz kraker = some crackers
• biraz ekmek = some bread
• biraz su = some water

This is very normal Turkish usage.

Even though crackers is plural in English, Turkish does not need krakerler here. The quantity word biraz already shows that you mean some.

Biraz usually means:

• a little
• some
• a bit

In this sentence, biraz kraker is best understood as some crackers or a few crackers.

It does not mean a precise amount. It just suggests a small quantity.

Both are in the simple past tense and mean we did something.

Yedik

From yemek = to eat

• ye- = stem
• -di- = past tense
• -k = we

So yedik = we ate

İçtik

From içmek = to drink

• iç- = stem
• -ti- = past tense
  (it appears as ti rather than di because of consonant harmony)
• -k = we

So içtik = we drank

This is because of consonant harmony in Turkish.

The past tense suffix is basically -DI, but its first consonant changes between d and t depending on the sound before it.

• After a voiced sound, you often get d
• After a voiceless sound, you often get t

So:

• ye- + di + k → yedik
• iç- + ti + k → içtik

The ç in iç is voiceless, so the suffix becomes -ti-.

Turkish normally prefers Subject–Object–Verb order, and the verb often comes at the end of the clause.

So:

• Toplantı uzayınca = When the meeting ran long
• biraz kraker yedik = we ate some crackers
• sonra çay içtik = then we drank tea

This verb-final tendency is one of the most important word-order habits in Turkish.

English says:

• we ate some crackers

but Turkish naturally says:

• some crackers we-ate
  → biraz kraker yedik

Sonra means then, afterwards, or later.

In this sentence, it connects the two actions in sequence:

1. biraz kraker yedik = we ate some crackers
2. sonra çay içtik = then we drank tea

So sonra helps show the order of events.

Yes. The sentence suggests both time order and a possible reason.

• Toplantı uzayınca... tells us the meeting went on longer than expected.
• Then the speakers ate crackers and drank tea.

That can simply mean:

• When the meeting ran long, we ate some crackers, then drank tea

But it also naturally implies:

• Because the meeting was taking so long, we ate some crackers and then had tea

Turkish often allows both readings at once.

Yes, uzamak is very commonly used in non-physical, figurative ways.

It can mean that something:

• lasts longer than expected
• drags on
• gets extended

So Toplantı uzadı means:

• The meeting ran long
• The meeting dragged on
• The meeting was extended

This is completely natural Turkish.

Yes. Although içmek literally means to drink, çay içtik is often translated naturally into English as:

• we drank tea
• we had tea

Both are fine depending on the tone of the translation.

If you want a more natural English sentence overall, you might even say:

• When the meeting ran long, we had some crackers and then tea.

But grammatically, Turkish is literally saying we drank tea.
