In any language, any one of us has certain words or phrases they like to say.
For me, in English, that includes “bedazzled” and “thingamagick” among others.
Howrver, is there some kind of overarching expression for these words? I can’t think of anything in English or my native German, and a quick Internet search didn’t find anything.
I can’t think of any.
But I’m a bit sad that the French-originating Bonmot is already taken in German (meaning a witty one-liner). It would have been a nice allusion to Bonbon (candy), like words that taste nice.
