zaum' :- 1. Nonsense; literally za 'trans' + um' 'sense; mind'. Coined by the Russian Futurists.
Or backformed from zaumnij. adj., meaningless.
Interesting, I had a classmate in elementary school whose last
name was Zaum. He was not meaningless, but few paid any
attention to him, very private kid: sort of living up to
some meaning of his name?
Zaum is also German for bridle or rein.
The repartee in these sites sure show the importance of
knowledge of more than one language.
