Questions & Answers about Om låssmeden ändå svarade i telefonen!
Why is there no main clause if the sentence starts with Om?
This is an independent optative clause, meaning it expresses a strong wish or desire and stands completely on its own. When you start a standalone sentence with Om and include a word like ändå or bara, it translates to "If only..." and doesn't need a follow-up clause.
Doesn't ändå usually mean "anyway" or "still"? What is it doing here?
Yes, those are its standard meanings. However, inside a standalone om-clause, ändå acts as a modal particle that intensifies the wish. Together with om, it creates the meaning "If only". You could also use bara here (Om låssmeden bara svarade...) with the exact same effect.
Why is svarade in the past tense if the speaker wants the locksmith to answer right now?
Just like in English ("If only he answered"), Swedish uses the past tense here to express an unreal or hypothetical situation in the present. The speaker wishes the locksmith were answering the phone right now, but he isn't.
Why do we say svarade i telefonen instead of just svarade telefonen?
In Swedish, you answer in the phone (svarar i telefonen). If you were to say svara telefonen without the preposition i, it would sound like you are answering a question asked by the physical phone device itself.
