Toplantı uzayınca biraz kraker yedik.

Uzayınca comes from the verb uzamak, which means to get longer, to last longer, or to drag on.

So in this sentence, toplantı uzayınca means something like:

• when the meeting went on too long
• when the meeting ran long
• since the meeting dragged on

The ending -ınca / -ince / -unca / -ünce often gives the idea of when, once, or sometimes because/as a result of, depending on context.

It breaks down like this:

• uza- = verb stem from uzamak
• -y- = buffer consonant
• -ınca = a suffix meaning when / once

So:

• uzamak = to become longer
• uzayınca = when it became longer / when it ran long

The y appears because the stem ends in a vowel and the suffix also begins with a vowel. Turkish often inserts y to connect them smoothly.

This is because of vowel harmony.

The suffix has different forms:

• -ınca
• -ince
• -unca
• -ünce

The form depends on the last vowel of the stem. In uza-, the last vowel is a, so the correct form is -ınca.

That gives:

• uza + ınca → uzayınca

It can suggest either one, depending on context.

In many cases, -ınca is best understood as:

• when
• once
• after

But in natural English translation, it can sometimes sound more like:

• since
• because

In this sentence, both ideas are close:

• When the meeting ran long, we ate some crackers.
• Since the meeting dragged on, we ate some crackers.

The Turkish form itself does not force a single English word every time.

Because toplantı is the subject of the subordinate clause toplantı uzayınca.

It is simply:

• toplantı = the meeting / a meeting

Turkish often does not use articles like the or a, so the bare noun can cover both, depending on context.

There is no need for a possessive or genitive ending here.
It is just the thing that became long / dragged on.

Biraz means a little, some, or a bit.

So:

• biraz kraker = some crackers

It does not necessarily mean a tiny amount in a strict mathematical sense. In everyday Turkish, it is a very common way to say some.

In Turkish, after words like biraz, numbers, and many quantity expressions, the noun usually stays singular in form.

So Turkish says:

• biraz kraker = some crackers
• iki kitap = two books
• çok insan = many people

Using the plural there would usually sound unnatural.

So even though English uses plural crackers, Turkish keeps kraker in the singular form after biraz.

Yedik is from the verb yemek, meaning to eat.

It breaks down as:

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

So yedik means:

• we ate

This is a complete verb form by itself, so Turkish does not need a separate word for we unless you want extra emphasis.

Because the verb already tells you the subject.

In yedik, the ending -k shows that the subject is we.

So:

• kraker yedik = we ate crackers

Adding biz is possible, but it would usually add emphasis, like:

• Biz biraz kraker yedik. = We ate some crackers.

Without emphasis, Turkish often leaves subject pronouns out.

Because Turkish normally places the main verb at the end of the sentence.

So the structure here is:

• Toplantı uzayınca = subordinate clause
• biraz kraker = object
• yedik = main verb

This end-position for the main verb is one of the most important word-order patterns in Turkish.

It is a loanword, ultimately from cracker.

In modern Turkish, kraker is a normal noun and is commonly used for crackers or crisp biscuits.

Like many loanwords in Turkish, it takes regular Turkish grammar endings when needed.

For example:

• kraker = cracker / crackers
• krakeri = the cracker / the crackers (object form, depending on context)
• krakerler = crackers

Yes, you could, and it is very similar in meaning.

Compare:

• Toplantı uzayınca...
• Toplantı uzadığında...

Both can mean when the meeting ran long.

A rough difference is:

• -ınca often feels a bit more like when/once/as soon as
• -dığında can feel a bit more neutral or descriptive: when/at the time that

In everyday use, both are possible here.

Here it is intransitive.

That means the meeting itself is the thing that became longer:

• Toplantı uzadı. = The meeting got longer / ran long.

If you wanted to say that someone made something longer, Turkish would use a different form, usually a causative verb.

So in this sentence, the idea is not someone extended the meeting, but rather the meeting dragged on / lasted longer.

Yes, very naturally.

Even though the form is literally close to when the meeting ran long, the overall meaning can easily imply cause:

• the meeting kept going
• therefore we got hungry or needed a snack
• so we ate some crackers

Turkish often leaves that relationship to context rather than spelling it out with a separate word like because.

A useful way to see it is:

[time/circumstance clause] + [object] + [main verb]

So:

• Toplantı uzayınca = when the meeting ran long
• biraz kraker = some crackers
• yedik = we ate

This is a very common Turkish pattern:

• Eve gelince kahve içtik.
• Ders bitince dışarı çıktık.

So your sentence follows a very normal and useful structure.
