FAQ (8)
It is common in speech, but in standard Croatian, it's better to say `Trebam ići` or just `Treba da idem`.
`Treba` is direct advice (should), while `trebalo bi` is more polite or hypothetical (ought to).
No, it can be used for things too, like `Neka sunce sja` (Let the sun shine).
Use `Ne trebam` + infinitive or `Ne bi trebalo da` + present tense.
No, it can also mean 'to need' something, like `Trebam novac` (I need money).
This is a dialectal and stylistic choice. 'Trebaš' is personal, 'treba' is impersonal. Both are understood.
Rarely. Usually, we use `hajde da` or `idemo` for 'let's'. `Neka ja to uradim` sounds like 'Let me be the one to do it'.
Using the phrase `Bilo bi dobro da...` (It would be good if...) or `Savjetovao bih vam da...` (I would advise you to...).

In Other Languages
should / let
Croatian 'treba' can be used impersonally with 'da', which English 'should' cannot.
deber / que + subjunctive
Croatian uses the present indicative after 'neka', not the subjunctive.
devoir / il faut que
French requires the subjunctive after 'il faut que', Croatian uses the indicative.
sollen / lassen
German 'sollen' is a modal verb with specific syntax, while 'trebati' is a regular verb.
~beki da / ~hou ga ii
Japanese advice is often more indirect and grammatically distinct from 'need'.
yajibu an / liyaf'al
Arabic has a specific mood (jussive) for these commands, while Croatian uses the present.
yīnggāi / ràng
Chinese verbs do not conjugate, making the Croatian system of personal/impersonal forms much more complex.
