Questions & Answers about Teidän olisi pitänyt tuoda kotivaranne väestönsuojaan.
How does olisi pitänyt translate to "should have"?
The verb pitää expresses obligation, like "must" or "to have to". When you put it in the conditional perfect form (olisi pitänyt), it literally means "would have had to". In natural English, this is exactly how we say "should have".
Why is the subject Teidän instead of Te?
Obligation verbs like pitää and täytyy always require their subject to be in the genitive case. This rule applies no matter what tense or mood the verb is in, so the basic pronoun te (you, plural) becomes teidän.
How is the word kotivaranne built?
It is a compound of koti (home) and vara (reserve or supply). A kotivara is an emergency preparedness stash. The -nne at the end is the possessive suffix for "your" (plural or formal).
Why doesn't the object kotivaranne have a case ending like -n or -t?
In necessity sentences, the object normally appears in the basic nominative form instead of the genitive -n. Furthermore, whenever you add a possessive suffix like -nne to a word, any -n or -t object endings drop off completely.
