I grew up in Norway and there's this idea in Europe of someone who breaks from corporate culture and hikes and camps a lot (called wandervogel in german). I also liked how when pronounced in Norwegian or Swedish it sounds like wander full. I like the idea of someone who is full of wander.
Same in Danish FWIW.
In English, I’d pronounce it very similar to “wonderful”.
In Swedish the G wouldn't be silent so it wouldn't really be all that much like "wonderful"; "vanderfugel" is the closest thing I could come up with for how I'd pronounce it with some leniency.
