Questions & Answers about De meddelte at de flytter, hvad vi synes er uventet.
Why is hvad used here to mean "which" instead of som or der?
The word hvad is acting as a sentence-level relative pronoun. It doesn't refer to a specific noun, but rather to the entire preceding clause (De meddelte at de flytter). You cannot use som or der here because those words must point back to a specific noun, not a whole situation.
Could I use hvilket instead of hvad in this sentence?
Yes, hvilket vi synes er uventet is also completely correct and means the exact same thing. When referring back to a whole clause, hvad and hvilket are generally interchangeable.
Why does the adjective uventet end in a -t?
It gets the neuter -t ending because it describes the entire situation of them moving, rather than a specific common-gender noun. In Danish grammar, an entire clause or situation is always treated as a neuter concept.
Why do we use synes for "think" here instead of tror?
You use synes because finding the move unexpected is your personal assessment. You use tror when you are guessing or stating a belief about unknown facts, but synes is used for subjective viewpoints and opinions.
Why is meddelte in the past tense but in the present tense?
