Croatians use 'treba' very frequently to avoid sounding too aggressive. It's a way of being polite by making the requirement about the situation, not the person.
In Dalmatia, you might hear 'tribat' instead of 'trebati', and it's often used even more loosely in daily speech.

常见问题 (8)
Yes, you can, and many Croatians do. However, in formal writing and standard grammar, `Treba mi` (Dative) is preferred.
`Treba` is about necessity (must/should), while `Valja` is about quality or advisability (it is good/worth).
Only if it's a personal construction where 'they' are the subject (e.g., 'Oni trebaju pomoć'). In impersonal rules, it is always `treba`.
Use the conditional impersonal: `Trebalo je` or `Trebalo bi mi` depending on the context.
It is slightly more formal or traditional, but still very much alive in proverbs and formal advice.
Yes, but usually with the Dative: `Treba mi (Dative) kava (Nominative)`.
This is a common construction in Bosnian and Serbian, and also in some Croatian dialects. In standard Croatian, `Treba + infinitive` is the norm.
It is `Ne valja`, which often means 'It is bad' or 'It is broken'.
