One other reason has been suggested is the language uses many idioms.

Maybe I’m mistaken, I’m half Danish and very belatedly learning Danish since I’d feel guilty learning any other second language first.

Duolingo goes up to A1 CEFR rating which like to refer to as Duplo level, I’m trying to strategise beyond.

Strangely I’ve been using Claude to help me put together a family tree a fair way mainly because it can “understand” Danish.

A surreal feeling when it can transcribe Danish church records written in gothic script from 150 years ago. Or accidentally proactively pick up probate pages a stitch them together.
