10. I understand and speak Norwegian, though not really fluently, and I can pick up some related words

in Icelandic (which hasn't changed much in a thousand years), but when I watch shows in Welsh I can't pick up any words at all, so I have to watch the subtitles every minute so I can't multitask at all or I lose the story.

What's cool about the Icelandic language is that it has a couple of letters nobody else except the Faroese uses any more: Þ, þ (thorn) and Ð, ð (eth). I know Welsh actually has vowels; the words when written just don't look like they have vowels.
