The stuff in the postscript isn't from the video, it's from a page on language that lets you listen to someone saying those words, first slowly and then at ordinary speed. I understand about agglutinative languages, but when you add suffixes and prefixes, those things usually add meaning. I'm just wondering, when the term seems to be something that's a simple noun (like frost), what actually is being expressed. Maybe it's "water that's chilled and white and that forms on the ground and on all surfaces"--something like that. I'd love to have a chance to think thoughts in that language.
