In all of your sentences, the verb needs to be placed before the subject, since you've already filled the first position with something else. The actual explanation requires a lot of grammar but here it is: In declarative main clauses the second element in the sentence must be the verb. I don't personally like to talk of an "inversion", since nothing is really being inverted. The rule is that the finite verb MUST be in second position (in declarative main clauses), it doesn't say that the subject has to appear before the verb. When something other than the subject is placed in the first position, the subject has to be put later in the sentence (again because the VERB has to be in second position). http://en.wikipedia.org/wiki/V2_word_order http://vfs.dansk.nu/en/8_2.asp

If a sentence begins with anything else than the subject, the verb must be before the subject.

Hey, Lora. It is a quite average way to speak Danish - as a foreigner. But in Danish, we change the "det" - so it ends the scentense. It is named "inversion" . When you say something about your experience - you refer to where something is happening. then, What happend - and - then - at last "det". "Det" refers to the place, - or the act. We have a grammar-rule - difficult. But if you want to see for further info. search the word ;"inversion". Hope you understand.. Kind rgds Annette
