"Sharawaggi" (or "sharawadgi") is a word of
Japanese (sometimes mistakenly attributed to
Chinese) origin adopted by
European languages in the
17th century. In Japanese, it means "
irregular" or "
asymmetrical," in a good sense, as in "the beauty of studied irregularity." But in Europe it took on more
connotations in
landscaping -- it described a
garden or grounds that were
wild-looking,
overgrown. (This was not a popular garden style at the time.) The word then was applied to humans who did not like
rules or what was considered
correct behavior.
Florence King uses it in
Reflections In A Jaundiced Eye to mean the "
let it all hang out" lack of correct behavior she considers a major problem in the modern
United States.
A Google search reveals that it is also the title of a 1990 poetry anthology edited by Robert Crawford and W. N. Herbert. The references to it online indicate that the poems are written in English or Scots (possibly both).
It is apparently also a gifts and furniture shop in Regina, Saskatchewan, Canada. (Often written "Indigo/Sharawaggi" as two stores are somehow connected.)
