Learn Croatian: Strah je velik, ali ja hoću pobijediti!

The full form hoću is used here to create the emphatic future tense. By using it instead of the short form ću, the speaker places strong emphasis on their determination, meaning "I WILL win!" Because hoću is also the present tense of "to want," it can also carry the meaning of "I want to win!" depending on the context.

Why is the pronoun ja included if Croatian usually drops subject pronouns?

Just like using the full form hoću, adding the pronoun ja (I) adds extra emphasis. The speaker is contrasting their strong personal determination against the feeling of fear.

Why is it velik instead of veliki?

When a masculine adjective comes after the verb "to be" to describe the subject, we use the short, indefinite form velik. The long form veliki is mostly used directly before a noun, like in the phrase veliki strah (the great fear).

If this is the future tense, why doesn't pobijediti drop its final -i?
