Ehh its not that interesting grammar wise. Just check the phonology, you will be slightly horrified but other than that its a very generic isolating northern germanic language. Huge amounts of vocab from proto-germanic(duh), english and french. The grammar is basically a remix of english. I still think its good to learn if you live in sweden which is kinda hard nowadays actually cause even swedish youth thinks theyre better off with english which is kinda sad.
