Şofben çalışmayınca sıcak su gelmedi; ben de duşu erteledim.

Çalışmayınca is built from:

• çalış- = to work, function
• -ma- = negation
• -yınca / -ınca = when, once, since, as soon as

So çalışmayınca literally means when it didn’t work or since it wasn’t working.

In this sentence, it has a causal sense:

• Şofben çalışmayınca... = Since the water heater wasn’t working...

Turkish often uses this -ınca / -ince form where English might prefer because.

The y is a buffer consonant.

Here is the structure:

• çalışma = not working
• -ınca gets attached after that

Because çalışma ends in a vowel, Turkish inserts y to make pronunciation smoother:

• çalışma + ınca → çalışmayınca

This happens often in Turkish when one suffix beginning with a vowel follows a form ending in a vowel.

They are similar, but not always identical in tone.

• çalışmayınca = when it didn’t work / since it didn’t work
• çalışmadığı için = because it didn’t work

In this sentence, both would work:

• Şofben çalışmayınca sıcak su gelmedi.
• Şofben çalışmadığı için sıcak su gelmedi.

But -mayınca / -meyince can feel a bit more like when that happened, this followed, while -dığı için is more directly explanatory: because.

This is a very natural Turkish way to talk about utilities like water, electricity, gas, internet, and so on.

• su gelmek = water comes
• elektrik gelmek = electricity comes
• internet gelmek can also be heard in casual speech

So sıcak su gelmedi literally means hot water didn’t come, but naturally it means there was no hot water or the hot water didn’t run.

English and Turkish simply package the situation differently.

Şofben means water heater, especially the kind used to heat water for washing or showering.

It is a borrowed word and is very common in everyday Turkish. In some contexts, people might also use more descriptive expressions, but şofben is a standard household word.

Because de here is the separate particle meaning too, also, as well.

• ben de = I too / I also
• bende = on me / at my place / in me, depending on context

So in this sentence:

• ben de duşu erteledim = so I also postponed the shower or I, in turn, postponed the shower

A useful rule:

• If de means also/too, it is written separately.
• If -de is the location suffix in/on/at, it is written attached.

Literally, yes, ben de means I too / I also. But in context, it often works more like:

• so I
• I then
• as a result, I

In this sentence, de does not necessarily mean that someone else postponed something too. It helps connect the second clause to the first and gives a natural conversational flow:

• Şofben çalışmayınca sıcak su gelmedi; ben de duşu erteledim.
• Since the water heater wasn’t working, there was no hot water, so I postponed the shower.

This use of de is very common in spoken and written Turkish.

Because duşu has the accusative ending, marking it as a definite direct object.

• duş = shower
• duşu = the shower

With many transitive verbs in Turkish, if the object is specific or definite, it takes the accusative:

• duşu erteledim = I postponed the shower
• bir duş erteledim would sound odd in most contexts, because you are usually referring to a specific planned shower

So duşu erteledim means you postponed that intended shower.

Yes, absolutely.

Both are natural, but they focus slightly differently:

• duşu erteledim = I postponed the shower
• duş almayı erteledim = I postponed taking a shower

The second version is a bit more explicit because it uses the verbal noun:

• duş almak = to take a shower
• duş almayı erteledim = I postponed taking a shower

In everyday Turkish, duşu erteledim is concise and natural.

Because the sentence reports completed events in the past.

• gelmedi = did not come
• erteledim = I postponed

The first clause sets up the situation:

• the hot water did not come

The second tells what the speaker did as a result:

• I postponed the shower

This is straightforward past narration.

Yes. Turkish word order is flexible, although some orders sound more neutral than others.

The original sentence is very natural:

• Şofben çalışmayınca sıcak su gelmedi; ben de duşu erteledim.

You could also say:

• Sıcak su gelmedi, çünkü şofben çalışmıyordu; ben de duşu erteledim.
• Ben de duşu erteledim, çünkü şofben çalışmayınca sıcak su gelmedi.

But the original version is compact and elegant because it presents the cause first, then the result.

Also note that Turkish often places the most important or newest information near the verb or before it, depending on emphasis.

Yes, it could.

The semicolon links two closely related clauses:

• Şofben çalışmayınca sıcak su gelmedi; ben de duşu erteledim.

It shows that the second clause follows naturally from the first.

Other possibilities:

• with a comma:
  Şofben çalışmayınca sıcak su gelmedi, ben de duşu erteledim.
• as two sentences:
  Şofben çalışmayınca sıcak su gelmedi. Ben de duşu erteledim.

The semicolon simply gives a slightly more polished written feel.

The given sentence is already natural, but in casual speech people might also say things like:

• Şofben çalışmayınca sıcak su gelmedi, ben de duşu erteledim.
• Şofben bozulmuştu, sıcak su gelmedi, ben de duşu erteledim.
• Sıcak su yoktu, ben de duşu sonraya bıraktım.

A few differences:

• bozulmuştu = had broken
• sonraya bırakmak = to leave for later / postpone

So the original sentence is perfectly good Turkish, just a little neat and written in style.
