Croatian verbs of mental activity form a tight cluster. Odlučiti (to decide), izabrati (to choose), and pretpostaviti (to assume) describe the process of arriving at a judgement, often followed by očekivati (to expect) and zahtijevati (to require). You can zamisliti (imagine) or sanjati (dream), and you may osjetiti (feel, sense) something. Uncertainty is expressed through sumnjati (to doubt) and certainty through priznati (to admit) or poreći (to deny). You can also uspoređivati (to compare) and, more concretely, otkriti (to discover) or sakriti (to hide) something. Typical sentences include Odlučio sam ostati (I decided to stay) and Pretpostavljam da znaš (I assume you know).
Communication and influence are handled by verbs such as predložiti (to suggest), savjetovati (to advise), obećati (to promise), upozoriti (to warn), and podsjetiti (to remind). You can prijetiti (to threaten) or uvjeriti (to convince), and you may need to zahvaliti (to thank) or ispričati se (to apologise). Disagreements are voiced with žaliti se (to complain), raspraviti (to discuss), and svađati se (to argue), while consensus uses složiti se (to agree) and ne slagati se (to disagree). Sample phrases include Savjetujem ti odmor (I advise you to rest), Priznajem da sam pogriješio (I admit I was wrong), and Upozorio sam te na opasnost (I warned you of the danger).
Verbs of permission, prohibition, and inclusion round out the social vocabulary. Dopustiti (to allow) stands against zabraniti (to forbid), while uključiti (to include) contrasts with isključiti (to exclude). Relations and dependence are expressed by utjecati (to influence), ovisiti (to depend on), pripadati (to belong to), and sastojati se (to consist of). Uspjeti (to succeed) versus ne uspjeti (to fail) captures outcomes. You might say Dopusti mi da pokušam (Allow me to try), Sve ovisi o tebi (It all depends on you), or Knjiga pripada knjižnici (The book belongs to the library).
