I wonder how the same Greek word gave eristic and heuristic with so different meanings.
Hey! the spelling robot checked 'eristic' in red!

i think schopenhauer wrote a book about an art of eristics... i never tried to use these rules :)) anyone did??

But it is charact - eristic that she doesn't recognise the word, suggesting 'erlang' was what you intended! Erlang, apparently is the unit for measuring the density of traffic flow. New to me. Would have been a good one for Hogwash perhaps.

Pleased to meet you, by the way!

Not sure about the connection with heuristic; according to the OED, heuristic stems from the Greek heurisko = find.

Edit: should add that 'she' is Ænigma, the spell-checker.

Eristic is a lot older than heuristic, which came to Englsih via some intermediates like German 'heuristisch' where it aquired something of today's 'exploratory problem-solving technique' meaning, I guess. The semantic lineage is pretty clear-cut and the meanings not altogether disparate.

Eris having been goddess of Discord, "eristic" is opposite to "helping to discover = heuristic".
