Şurup bitince eczaneye uğramadan olmaz.

Bitince comes from the verb bitmek (to finish, to run out, to be used up) plus the suffix -ince / -ınca, which often means when or once.

So:

• bitmek = to finish / run out
• bitince = when it finishes / when it runs out

In this sentence, Şurup bitince means when the syrup runs out.

This suffix is very common in Turkish:

• gelince = when he/she comes
• gidince = when he/she goes
• yapınca = when he/she does it

So the first part of the sentence is a time clause.

Because here şurup is the thing that is finishing or running out, so it acts like the subject of bitmek.

Compare:

• Şurup bitince = when the syrup runs out
• Şurubu bitirince = when someone finishes the syrup

This is a very important Turkish distinction:

• bitmek = to finish / be finished / run out
  
  • intransitive
• bitirmek = to finish something
  
  • transitive

So:

• Şurup bitince = the syrup itself runs out
• Şurubu bitirince = someone uses it up / finishes it

Because uğramak usually takes the dative case: -e / -a, meaning to / into / by a place.

So:

• eczane = pharmacy
• eczaneye = to the pharmacy

The extra y is a buffer consonant, because eczane ends in a vowel:

• eczane + e would be awkward
• so Turkish inserts y: eczaneye

Examples with uğramak:

• Markete uğradım. = I stopped by the market.
• Arkadaşa uğrayacağım. = I’ll stop by my friend’s place.
• Eczaneye uğramak = to stop by the pharmacy

So eczaneye is exactly what the verb needs here.

Uğramadan means without stopping by.

It is formed from:

• uğramak = to stop by, drop in
• -madan / -meden = without doing

So:

• uğramadan = without stopping by

This suffix is very common:

• yemeden = without eating
• gitmeden = without going
• söylemeden = without saying

In the sentence, eczaneye uğramadan olmaz literally means something like:

It won’t do without stopping by the pharmacy.

That sounds more natural in English as:

We’ll have to stop by the pharmacy.

Because -madan olmaz is a common idiomatic pattern in Turkish meaning:

• one cannot do without ...
• it won’t do not to ...
• you have to ...
• it’s necessary to ...

So:

• eczaneye uğramadan olmaz = we can’t do without stopping by the pharmacy
• more natural English: we have to stop by the pharmacy

It is slightly more idiomatic and indirect than uğramak lazım or uğramak gerek.

Compare:

• Eczaneye uğramak lazım. = It’s necessary to stop by the pharmacy.
• Eczaneye uğramadan olmaz. = We can’t really avoid stopping by the pharmacy.

The second one often feels a bit more like there’s no way around it.

Literally, olmaz means it doesn’t become / it won’t be / it’s not possible / it won’t do, depending on context.

In this sentence, it is part of the fixed pattern -madan olmaz, so the whole idea is:

• it won’t do without ...
• it’s not possible not to ...
• you have to ...

So olmaz here does not simply mean it doesn’t exist or it is impossible in a literal, isolated way. Its meaning comes from the whole construction.

A few similar examples:

• Çalışmadan olmaz. = You can’t do it without studying / You have to study.
• Beklemeden olmaz. = We have to wait.
• Konuşmadan olmaz. = We need to talk.

Turkish often leaves the subject unstated when it is obvious, general, or unimportant.

In Şurup bitince eczaneye uğramadan olmaz, there is no explicit subject, so it can mean something like:

• we’ll have to stop by the pharmacy
• you’ll have to stop by the pharmacy
• one has to stop by the pharmacy

The exact interpretation depends on context.

This is very normal in Turkish, especially with impersonal expressions like:

• lazım
• gerek
• şart
• olmaz

So the sentence is deliberately general and natural.

Very often, yes, but not always. Uğramak has a few related meanings depending on context.

Common meanings include:

• to stop by / drop in
• to visit briefly
• in some contexts, to be subjected to something

In this sentence, the meaning is clearly:

• to stop by the pharmacy

Examples:

• Akşam sana uğrarım. = I’ll stop by your place this evening.
• Markete uğradık. = We stopped by the market.
• Kazaya uğradı. = He/She had an accident.
  
  • This is a different use, not the one meant here.

So in your sentence, uğramak is the everyday stop by meaning.

Yes, the word order is natural, but Turkish allows some flexibility.

The given sentence:

• Şurup bitince eczaneye uğramadan olmaz.

is perfectly natural and means roughly:

• When the syrup runs out, we’ll have to stop by the pharmacy.

Possible alternatives include:

• Şurup bitince eczaneye uğramak lazım.
• Şurup bitince eczaneye uğramamız gerekecek.
• Şurup bitince eczaneye uğramadan olmaz artık.

They are similar, but the tone changes slightly:

• uğramak lazım = more direct
• uğramamız gerekecek = more explicit and future-oriented
• uğramadan olmaz = more idiomatic, there’s no avoiding it

So the original sentence sounds very natural and conversational.

Yes. In many contexts, -ince / -ınca can be translated as either:

• when
• once
• after

The best English version depends on what sounds natural.

So Şurup bitince could be understood as:

• when the syrup runs out
• once the syrup runs out
• after the syrup runs out

All of these are close in meaning here.

If Turkish wants to sound more explicitly like after, it can also use:

• bittikten sonra = after it has finished/run out

So:

• Şurup bitince = when/once/after the syrup runs out
• Şurup bittikten sonra = after the syrup has run out

In everyday speech, bitince is very common and natural.

Yes: the most useful thing to remember is the pattern:

verb + -madan/-meden + olmaz

This often means:

• you have to ...
• you can’t do without ...
• there’s no way around ...

Examples:

• Gitmeden olmaz. = We have to go.
• Sormadan olmaz. = We have to ask.
• Denemeden olmaz. = You have to try.
• Dinlenmeden olmaz. = You need to rest.

So instead of translating word by word, it is better to learn the whole pattern as an expression.

For this sentence, a good natural understanding is:

When the syrup runs out, we’ll have to stop by the pharmacy.
