Questions & Answers about Det bästa är sidoläget för att patienten ska andas.
Why do we need the word 'ska' here instead of just saying 'för att patienten andas'?
When using för att to mean 'so that' with a new subject (patienten), Swedish typically requires a modal verb like ska (present/future) or skulle (past) to express intention or purpose. If you just said för att patienten andas, it would translate to 'because the patient is breathing' rather than 'in order for the patient to breathe.'
Could I just use an infinitive and say 'för att andas' instead?
Not in this sentence. You can only use för att + infinitive when the subject doing the action is the same in both clauses. Since the main clause is about det bästa (the best thing) and the second clause introduces a new subject (patienten), you have to use a full subordinate clause to show who is doing the breathing.
'Det' is an ett-word, so why is it 'det bästa' and not 'det bäst'?
Bästa is a superlative adjective functioning here as a noun meaning 'the best thing'. Because it follows the freestanding definite article det, it must take the definite adjective ending, which is -a, regardless of the gender of the noun it replaces.
Does the '-s' on the end of 'andas' make it a passive verb?
