Questions & Answers about Hallan on määrä tulla yöllä.
Why is halla in the genitive case (hallan) instead of the nominative?
In this sentence structure, the entity that is supposed to do something acts as the logical subject and must be in the genitive case. The literal translation is closer to 'It is the frost's set schedule to come.' This genitive subject rule applies to both on määrä and on tarkoitus constructions.
Could I use on tarkoitus instead of on määrä here?
Not naturally. While both constructions take a genitive subject and an infinitive, on tarkoitus implies a conscious human intention or plan. Because frost is a weather phenomenon and cannot have personal intentions, on määrä (which implies an external schedule, expectation, or forecast) is the correct choice.
Doesn't the word määrä usually mean 'amount' or 'quantity'?
Yes, in most everyday contexts, määrä translates to 'amount'. However, it also carries the historical idea of a fixed point, limit, or destiny (as seen in the word määränpää, meaning 'destination'). In the fixed phrase on määrä, it conveys the idea of a predetermined event or schedule.
Could I say Hallan pitäisi tulla yöllä to mean the same thing?
