Questions & Answers about Kapteeni antoi käskyn valmistautua, koska miehistöllä oli valmius lähteä.
Why do we use the first infinitive for both valmistautua and lähteä here?
They act as complements to the abstract nouns käsky (order) and valmius (readiness). Just like in English, many Finnish abstract nouns expressing will, intention, capability, or obligation govern the basic 1st infinitive. They act as modifiers answering what kind of order or what kind of readiness.
Why is käskyn in the accusative (genitive shape) but valmius is in the nominative? Does the infinitive affect this?
The attached infinitive does not affect the case of the noun. The case is determined purely by the noun's role in its own clause. käskyn is the total object of the active verb antoi (the captain gave the order), so it takes the genitive-like accusative. valmius, however, is the subject of the possessive structure miehistöllä oli (the crew had), so it must be in the nominative.
Could we say miehistö oli valmis lähtemään instead of using the noun valmius?
Yes! However, notice the grammar shift: using the adjective valmis (ready) requires the 3rd infinitive illative (lähtemään). Using the abstract noun valmius (readiness) requires the 1st infinitive (lähteä). The noun structure used in this sentence sounds slightly more formal and official, which fits the context of a captain's order perfectly.
