Any language, explain what it means if it’s not English.
For example (as a non-native speaker) I’ve always liked the English word ‘unprecedented’, mostly in the context of fiction. Especially if it paints some entity to be really mystical or wondrous or it’s own never before seen order of magnitude in any way.
I searched for the meaning and got a video clip instead of a musical about the word, still don’t know the meaning and I am fine with that, now I know how to sound precocious ;)
