Learn Croatian: Možemo ozdraviti kroz terapeutski proces. - We can get well through a therapeutic process.

In physical contexts, kroz means physically moving through a space. In this sentence, it is used abstractly to express the means or method of achieving something. It shows that the therapeutic process is the path or method we use to get well.

Why do terapeutski and proces look like they are in the nominative case if kroz requires the accusative?

The preposition kroz always takes the accusative case. However, proces is an inanimate masculine noun. For inanimate masculine nouns, the accusative form is identical to the nominative form, which is why terapeutski proces doesn't change its ending here.

Could we express "through a therapeutic process" using the bare instrumental case instead of kroz?

You might remember using the bare instrumental case for tools or physical means. However, for abstract methods, phases, or processes like this one, Croatian strongly prefers using kroz with the accusative to express "by means of" or "through".

What is the difference in meaning if we swap ozdraviti with its imperfective pair ozdravljivati?

Ozdraviti is perfective, meaning it focuses on the completed result of getting well. If you used ozdravljivati, the sentence would mean "We can be healing" or "We can be getting well", focusing on the ongoing duration rather than reaching the final goal of full recovery.
