Questions & Answers about Ti ideš kući.

What part of speech is Ti and is it mandatory?

Ti is the 2nd person singular personal pronoun (“you”). It’s not mandatory because the verb ending -š in ideš already indicates “you.” You include Ti for emphasis, contrast, or clarity; otherwise, Ideš kući alone means “You are going home.”

What is the verb ideš and how is it formed?

ideš is the present tense, 2nd person singular form of the verb ići (to go). The stem is id-, and the ending -eš marks “you.” Conjugation in present tense:
• ja idem
• ti ideš
• on/ona/ono ide
• mi idemo
• vi idete
• oni/one/ona idu

Why is kući used instead of kuća, and what case is it?

kući is the dative/locative singular form of kuća (house). In ići kući, it functions adverbially as “to home.” You cannot use the nominative kuća or the accusative kuću here—kući is the correct case for “going home.”

Why is there no preposition before kući? How would you say “into the house”?

No preposition is needed because kući already means “to home.” If you want “into the house” (entering a building), you use a preposition + accusative:
• Idem u kuću – “I’m going into the house.”
Here u requires the accusative kuću, and the meaning shifts from “going home” to “entering the house.”

How do you turn Ti ideš kući into a question (“Are you going home?”)?

Two common ways:

1. Insert the question particle li after the verb (pronoun optional):
   • Ideš li kući?
2. Keep the word order and rely on rising intonation (spoken):
   • Ti ideš kući?

How do you make the sentence negative?

Place the negation particle ne before the verb:
• Ti ne ideš kući.
You can also drop Ti:
• Ne ideš kući.

Is the word order fixed, and can changing it add emphasis?

Croatian word order is flexible because cases show grammatical roles.
• Ti ideš kući – neutral (S-V-Adv).
• Kući ti ideš – emphasizes where you’re going.
• Ti kući ideš – stresses the person going home.
Meaning stays the same; only emphasis shifts.

Can you say doma instead of kući, and what’s the difference?

Yes. (Ti) ideš doma is colloquial for “you’re going home.” doma is an adverb meaning “home,” not a noun form. It’s very common in speech and a bit less formal than kući.
