Rule

We write "No" with predicates (such as "you know", "you can", "you have to", "it's worth it") separately, just like with verbs.

Why so?

The word "knows" is a predicative - an impersonal form that behaves like a verb - so we write the negative "no" separately before it, exactly as in "I don't know" or "I don't have." The combined entry "unknown" is incorrect. The same rule applies to other predicates: "you can't", "you don't have to", "it's not worth it". Note: there is also a noun "unknown" (e.g. in mathematics), written collectively - but it is a different word, with a different meaning and a different grammatical function.

Usage examples

  • It is not known when the renovation will be completed.
  • To this day it is not known what happened.
