Questions & Answers about Vůbec neznám řešení.

What does vůbec add to the sentence?

Vůbec strengthens the negation. In this sentence, it means something like at all, in any way, or really not.

So:

• Neznám řešení. = I don’t know the solution.
• Vůbec neznám řešení. = I don’t know the solution at all. / I have no idea what the solution is.

It is a very common word with negatives in Czech.

Why is it neznám and not something like nejsem znát or nevím?

The verb here is znát = to know, to be familiar with.

Neznám means I do not know / I am not familiar with.

Czech often distinguishes between:

• vědět = to know a fact, to know information
• znát = to know a person, place, thing, or be familiar with something

In this sentence, řešení is treated as something like the solution as an entity, so znát is natural.

Compare:

• Nevím odpověď. = less natural in standard Czech
• Neznám odpověď. = I don’t know the answer
• Nevím, jak to vyřešit. = I don’t know how to solve it

So neznám řešení is a normal Czech way to say I don’t know the solution.
