Learn Croatian: Direktor uvijek radi pošteno. - The director always works honestly.

In Croatian, you can easily turn many adjectives into adverbs by using their neuter singular form. The base adjective for honest is pošten. By adding the neuter ending -o, it becomes the adverb pošteno (honestly), which describes how the director works.

Could pošteno also be an adjective?

Yes! Out of context, pošteno looks exactly like a neuter adjective. For example, in the phrase pošteno dijete (an honest child), it acts as an adjective describing the noun. But in this sentence, because it describes the verb radi (works), we know it is functioning as an adverb.

Why are uvijek and pošteno placed where they are in this sentence?

Croatian word order is quite flexible. Adverbs of time like uvijek (always) usually go right before the verb. Adverbs of manner like pošteno (honestly) often go right after the verb. However, you could also say Direktor uvijek pošteno radi and it would still be perfectly correct.

Why is there no word for 'the' before direktor?

As a quick refresher, Croatian does not use definite (the) or indefinite (a/an) articles at all. The single word direktor can mean director, a director, or the director depending entirely on the context.
