Questions & Answers about Odotan sinua iltaan asti.
Because sinua is the partitive form of sinä (you), and here you is the object of the verb odottaa (to wait for).
- sinä = you as the subject
- sinua = you as the object, in the partitive
So:
- Sinä odotat. = You are waiting.
- Minä odotan sinua. = I am waiting for you.
In Finnish, odottaa commonly takes its object in the partitive. This is just the normal pattern of the verb.
So you say:
- odotan sinua = I’m waiting for you
- odotamme bussia = we’re waiting for the bus
A useful way to think about it is that waiting is usually seen as an ongoing, not-yet-completed action, and that often goes together with the partitive in Finnish.
