Learn Polish: To, co ujawni to nagranie, jest szokujące. - What this recording will reveal is shocking.

When "what" means "the thing that" in English, Polish usually pairs the demonstrative pronoun to (that) in the main clause with the relative pronoun co (what) in the subordinate clause. You can think of it literally as "That, which this recording will reveal, is shocking."

Is to nagranie the subject or the object of ujawni? It comes after the verb!

to nagranie (this recording) is the subject. Polish word order is very flexible, and putting the subject after the verb in relative clauses is common and often sounds more natural. The object of ujawni is actually the relative pronoun co (what).

Why does ujawni mean "will reveal" rather than just "reveals"?

The verb ujawnić is perfective, meaning it focuses on a completed action. In Polish, when you conjugate a perfective verb using present-tense endings, it automatically creates the future tense. So, ujawni means "it will reveal".

Why does the adjective szokujące end in -e?

szokujące takes the neuter singular ending -e because it describes the neuter pronoun to (that) from the very beginning of the sentence. When an adjective describes a generic concept or an entire clause introduced by to, it must be in the neuter form.
