Questions & Answers about Tko će graditi tvoju kuću?
Why use the imperfective verb graditi here instead of a perfective verb like izgraditi?
The imperfective aspect is used because the question focuses on the ongoing process of building, which is why it translates to 'will be building' rather than just 'will build'. If you wanted to ask 'Who will complete the building of your house?', you would use the perfective verb izgraditi.
Why is the word order će graditi instead of gradit će?
In Croatian, short unstressed words (enclitics) like će must go in the second position in a sentence. Since the question word tko takes the first position, će naturally follows it, and the infinitive graditi comes after.
Why do the words tvoja and kuća change to tvoju kuću?
They are the direct object of the action (the thing being built), so they must be in the accusative case. For feminine nouns ending in -a, like kuća, the ending changes to -u in the accusative, and the possessive word tvoja changes to match it.
Why do we use će (the 'he/she/it' form of the future auxiliary) when we do not know who the person is?
In Croatian, the question word tko (who) is always treated grammatically as a third-person singular subject. Therefore, it always pairs with će, just as it would if the subject were on (he) or ona (she).
