Reminds me of a great translation I struggled a bit at first. Gimli from Lord of the Rings is named in English: Gimli, son of Glóin. In the German translation his name is Gimli Glóinssohn. So back to English it would be Gimli Glóinson
If I remember my childhood’s Carroux translation correctly she used “Gimli, Gloins Sohn”, so not the Scandinavian construction, but a grammatically correct, but still archaic sounding, German construction which is near the original and still got the vibe of Gloinson.
Translation is tricky business.
So how the mirror of Erised had do get a proper backwards name in Norwegian, the O.W.Ls needed a fun acronym as well, Tom Marvolo Riddle is translated as Tom Dredolo Venster to make a matching sentence akin to how it in English is I am Lord Voldemort. Gotta make the songs and poems rhyme, etc.
The Norwegian translation is a work of love, and the translator Torstein Bugge Høverstad got quite famous here for his work.
