Questions & Answers about Sinun täytyy kiirehtiä, koska koulu alkaa kohta!
Why is it sinun instead of sinä?
With necessity verbs like täytyy (must / have to), the person who has to do the action is put in the genitive case. Literally, the sentence is built like 'Of you it is necessary to hurry'.
Why is the verb just täytyy and not conjugated to match 'you'?
Necessity verbs are impersonal. They always stay in the third-person singular form, no matter who is doing the action. The main verb that follows it, kiirehtiä, stays in its basic dictionary form (infinitive).
The current lesson is about object cases with necessity verbs. Where is the object in this sentence?
There isn't one! The verb kiirehtiä (to hurry) doesn't take an object. If you added an object, like 'You must buy a car' (Sinun täytyy ostaa auto), the object auto would be in the basic nominative form, following the special rule for necessity verbs you are learning right now.
Is kohta the only way to say 'soon'?
You might also know the word pian (soon). They are very similar in meaning, but kohta is extremely common in everyday speech and often implies something is going to happen in just a few moments.
