Learn Swedish: Jag undrar om försäkringen täcker en repad dörr. - I wonder if the insurance covers a scratched door.

Here, repad is a past participle (a verb form used as an adjective) describing dörr (door). Because dörr is an en-word (en dörr) and singular, the participle takes the en-form, which ends in -ad. If it were describing an ett-word, it would be repat, and for plural words, it would be repade.

I learned that om means 'about'. Why does it mean 'if' in this sentence?

While om often means 'about' as a preposition (like in prata om - to talk about), it is also the Swedish word for 'if' or 'whether' when it joins two parts of a sentence. Jag undrar om directly translates to 'I wonder if' or 'I wonder whether'.

Does the word order change after om?

Yes, because om introduces a subclause (a dependent part of the sentence). The subject still comes before the verb (försäkringen täcker), but if you wanted to add inte (not), it must go before the verb in a subclause. For example, 'if the insurance does not cover' would be om försäkringen inte täcker, which is a special rule for subclauses.

How do I know if försäkring is an en-word or an ett-word?
