Dosud nemám odpověď.

Dosud means so far, up to now, or until now.

In this sentence, it tells you that the situation is true at the present moment: the speaker still does not have an answer.

A close English idea would be:

• So far, I don’t have an answer.
• I still don’t have an answer.
• Up to now, I don’t have an answer.

Dosud is understandable and correct, but in everyday speech many speakers often use zatím or ještě in similar contexts.

Nemám is the 1st person singular present tense of mít (to have) with negation.

• mám = I have
• nemám = I do not have / I don’t have

So:

• Dosud nemám odpověď. = So far I don’t have an answer.

This is a very common pattern in Czech:

• mám čas = I have time
• nemám čas = I don’t have time

Czech often omits personal pronouns when they are not needed, because the verb ending already shows who the subject is.

Here, nemám clearly means I do not have, so já is unnecessary.

You could say:

• Dosud nemám odpověď.
• Já dosud nemám odpověď.

Both are grammatical, but the version without já is more natural in many situations.

Adding já usually gives extra emphasis, for example:

• Já dosud nemám odpověď, ale on už ano.
  I still don’t have an answer, but he already does.

Because odpověď is the direct object of nemám (I don’t have), so it is in the accusative case.

The noun is:

• nominative: odpověď = answer
• accusative: odpověď

So in this case, the nominative and accusative forms are the same.

That is why you do not see any visible change, even though the noun is functioning as an object.

Yes. Odpověď is a feminine noun.

It belongs to a group of feminine nouns that end in a soft consonant, and many of them change in forms like these:

• nominative singular: odpověď
• genitive singular: odpovědi
• dative singular: odpovědi
• accusative singular: odpověď
• instrumental singular: odpovědí

You do not need all the forms just to understand this sentence, but it helps explain why the noun behaves the way it does.

Yes, absolutely. Zatím nemám odpověď is very natural and probably more common in everyday spoken Czech.

Roughly:

• dosud = so far / up to now
• zatím = for now / so far
• ještě nemám odpověď = I still don’t have an answer

The differences are mostly about style and nuance, not basic meaning.

Very roughly:

• dosud can sound a bit more formal or written
• zatím is very common in conversation
• ještě strongly highlights still/not yet

They overlap, but they are not exactly the same.

• Dosud nemám odpověď. = So far / up to now, I don’t have an answer.
• Ještě nemám odpověď. = I still don’t have an answer / I don’t have an answer yet.

Ještě often focuses more on the idea that the answer may come later.
Dosud focuses more on the time span up to the present.

In many real situations, both can work.

Yes. Czech word order is relatively flexible, and changing it can shift the emphasis.

Neutral version:

• Dosud nemám odpověď.

Other possible versions:

• Odpověď dosud nemám.
• Dosud odpověď nemám.
• Nemám dosud odpověď.

These all mean roughly the same thing, but they sound slightly different in emphasis or style.

A learner should usually treat Dosud nemám odpověď as a good, natural default.

Yes. Czech normally uses the present tense here: nemám = I don’t have.

Czech does not match English tense usage word-for-word. English may use:

• I don’t have an answer yet
• I still don’t have an answer
• I haven’t got an answer yet

Czech naturally says:

• Ještě nemám odpověď.
• Dosud nemám odpověď.
• Zatím nemám odpověď.

So the Czech present tense is exactly what you would expect here.

A helpful rough guide is:

od-po-vyetch
or more carefully: ot-po-vyechď

A few important points:

• Stress in Czech is almost always on the first syllable: ODpověď
• ě often affects the previous consonant and is not pronounced like plain e
• Final ď is a soft d-sound

You do not need to pronounce it perfectly at first, but try to keep:

• first-syllable stress
• the soft ending ď

Because Czech has no articles.

English distinguishes:

• an answer
• the answer

Czech usually leaves that information to:

• context
• word order
• intonation
• sometimes other words

So odpověď can mean:

• an answer
• the answer

In this sentence, English naturally translates it as an answer, but Czech itself does not use a separate word for a/an.

It is neutral and correct.

What affects the tone most is dosud:

• Dosud nemám odpověď. sounds natural, but a bit more formal or written than some alternatives.
• Zatím nemám odpověď. often sounds more everyday and conversational.
• Ještě nemám odpověď. is also very common and natural.

So the sentence is not stiff or strange, but it is slightly more formal than the most casual spoken option.

Not exactly.

Dosud nemám odpověď literally means So far I don’t have an answer.

That can overlap in meaning with English I still don’t know the answer, but Czech uses a different verb if you want to say know directly:

• Dosud neznám odpověď. = I still don’t know the answer.

The sentence with mít focuses on having/possessing an answer, not on knowing it directly. In many contexts, though, the practical meaning may be very similar.
