Questions & Answers about Haluan nähdä hyvän aloituslyönnin, sillä snooker on vaikea peli.
Why is the object hyvän aloituslyönnin in the genitive-looking accusative case instead of the basic nominative?
This sentence demonstrates object case inheritance! The main verb haluan (I want) is a standard personal verb, which dictates that its total object takes the accusative case ending in -n. The infinitive verb nähdä (to see) doesn't decide the case on its own; it simply inherits this rule from the main verb haluan.
If the sentence started with an impersonal necessity verb like Minun täytyy (I must) instead of Haluan, would the object stay the same?
No, it would change to the nominative-looking accusative: Minun täytyy nähdä hyvä aloituslyönti. The infinitive nähdä inherits its object rules from the very first verb in the chain. Since impersonal necessity verbs like täytyy require a nominative-looking object, the object drops the -n ending.
Could I use the partitive case hyvää aloituslyöntiä here, and how would it change the meaning?
You could, but it shifts the aspect. By using the total object hyvän aloituslyönnin, you mean you want to see one whole, specific, and complete break shot. Using the partitive hyvää aloituslyöntiä would imply an ongoing process, such as watching the shot as it happens, or just seeing some good break-shooting without a clear endpoint.
Why does the sentence use sillä for because instead of the more common koska?
