Swedish Supine w/o Aux. Verb
I was reading the newspaper today, and came across the following sentence: '[m]en Leclerc sade på söndagen att hans uttalande tagits ur sitt sammanhang och att han inte vid något tillfälle varit emot begravningen.' I see two instances of the supine, 'tagits' and 'varit', but no accompanying form of 'att ha'. The sentence makes sense, but is omitting 'har' common/dialectal/allowed? What's going on here? Is this an advanced topic not covered by Duolingo?
It is allowed in some cases, and actually pretty common in written Swedish. Although I would guess many swedish native writers are not even aware that they (sometimes) do omitt the "har" (or "hade"). I wouldn't worry too much about it unless you're very advanced - it is never wrong to keep the "har"/"hade".
Har/hade can be omitted in subclauses (begin with "att") and relative clauses (begin with "som"). Possibly other places too, those are the two I can think of now. It's equally common in speech as well, and the same rules apply. IMO omitting them gives a better flow to the sentence and improves the style.
