Wir haben dasselbe Problem.

In standard German, dasselbe is normally written as one word when it means the same.

• dasselbe Problem = the same problem
• dieselbe Idee = the same idea

This is a fixed form built from der/die/das + selbe.

You may sometimes see separate writing in older texts or in very specific stylistic situations, but for learners, the correct form to use here is dasselbe.

This is one of the most common questions.

• dasselbe means one and the same
• das gleiche means an identical/similar one

So:

• Wir haben dasselbe Problem.
  = We both have the very same problem.

• Wir haben das gleiche Problem.
  = We have the same kind of problem / an identical problem.

In everyday speech, many native speakers use them quite loosely, and das gleiche is very common where strict logic would prefer dasselbe. But the traditional distinction is still useful to know.

Because dasselbe Problem is singular.

The sentence means that we have one shared problem. The subject wir is plural, but the thing we have is singular:

• wir = we
• haben = have
• dasselbe Problem = the same problem

If you wanted the plural, you would say:

• Wir haben dieselben Probleme.
  = We have the same problems.

It is in the accusative case, because it is the direct object of haben.

Breakdown:

• Wir = subject, nominative
• haben = verb
• dasselbe Problem = direct object, accusative

Since Problem is neuter (das Problem), the accusative singular form is:

• dasselbe Problem

For neuter singular, nominative and accusative look the same, so you do not see a visible change here.

Because dasselbe behaves like a determiner word, similar to an article, and its ending changes depending on gender, case, and number.

Here, Problem is:

• neuter
• singular
• accusative

So the correct form is:

• dasselbe Problem

Compare:

• derselbe Mann = the same man
• dieselbe Frau = the same woman
• dasselbe Problem = the same problem
• dieselben Leute = the same people

Because dasselbe already includes the article-like part.

It works a bit like a combined form. You do not say:

• das dasselbe Problem ❌

You simply say:

• dasselbe Problem ✅

The word already carries the function that an article would normally have.

Because German main clauses normally follow the verb-second rule.

In a basic statement:

• Wir = first element
• haben = second element
• dasselbe Problem = the rest of the sentence

So:

• Wir haben dasselbe Problem.

This is standard German word order for a simple main clause.

If you move another element to the front, the verb still stays second:

• Dasselbe Problem haben wir auch.

No. Even though they look similar, they are different things.

• dass = conjunction, meaning that
• dasselbe = determiner/pronoun meaning the same

So in this sentence, dasselbe has nothing to do with the conjunction dass.

A learner may notice the spelling and wonder about it, but grammatically they are separate words.

Yes. It changes just like other German article-type words.

A few important forms are:

• derselbe Mann = the same man
• dieselbe Frau = the same woman
• dasselbe Problem = the same problem
• dieselben Kinder = the same children

Some case examples:

• mit demselben Problem = with the same problem
• wegen desselben Problems = because of the same problem

So when you learn dasselbe, it is best to learn it as a word that declines.

Yes, very much so in this sentence.

German often uses haben in the same way English uses have to talk about possessing or experiencing something:

• Ich habe Hunger. = I am hungry.
• Wir haben ein Problem. = We have a problem.
• Wir haben dasselbe Problem. = We have the same problem.

So this sentence is very natural and direct in German.

A simple learner-friendly pronunciation guide would be:

• Wir ≈ veer
• haben ≈ HAH-ben
• dasselbe ≈ DAHSS-EL-buh
• Problem ≈ proh-BLEM

A few useful notes:

• w in German sounds like English v
• h is pronounced in haben
• the stress in Problem is on the second syllable: pro-BLEM
• r in standard German is usually not pronounced like a strong English r

So the whole sentence sounds roughly like:

veer HAH-ben DAHSS-EL-buh proh-BLEM

Yes, you definitely could, and many native speakers would say exactly that.

• Wir haben dasselbe Problem.
• Wir haben das gleiche Problem.

Both are common and usually understood the same way in everyday conversation.

If you want to be more precise according to the traditional distinction:

• dasselbe Problem = literally the very same problem
• das gleiche Problem = an identical kind of problem

But in normal speech, the second version is extremely common and often interchangeable.
