'Tradiciones Peruanas", what a wonderful reading. Very challenging castillian spanish, I am impressed.
This was one of my favorites when growing up in Peru. My father used to quote Ricardo Palma a lot.
.... y demás enguinfingalfas que trae consigo un litigio
, Yes, this must be one word created by Don Ricardo. In this context, it would mean: all the nonsense (or mess) brought up by a lawsuit.
Enjoy your reading.
