Modal verbs in Serbian grammar are crucial in expressing mood, ability, necessity, or other conditions. They are highly irregular and often have different conjugations for different tenses. Some of the most common modal verbs in Serbian are ‘moฤi’ (can), ‘morati’ (must), ‘hteti’ (want), and ‘trebati’ (need). Their usage provides depth and context to a sentence and lets the speaker relay their emotions, obligations, possibilities, and necessities effectively.
