Learn Croatian: Bit ću u novoj raketi. - I will be in the new rocket.

When the future tense helper word (ću, ćeš, će...) comes right after the main verb, the main verb drops its final -i. So, the infinitive biti (to be) becomes bit. This rule applies to all Croatian verbs that end in -ti.

Can I include the word for 'I' and say Ja ću biti u novoj raketi?

Yes, you can! If you use the pronoun ja (I), the helper word ću must come right after it. Because the main verb now comes later in the sentence, it keeps its full form: Ja ću biti u novoj raketi. However, Croatian usually drops pronouns, which is why we start with the verb and get Bit ću.

Why did raketa change to raketi in this sentence?

The preposition u (in) requires the locative case when you are talking about a static location, meaning where something is located right now rather than moving towards it. For feminine nouns that end in -a like raketa, the locative ending changes the -a to an -i.
