You wrote the pleural of "schema" as "schemata."
My heart is warmed.
Americans write that as "schemas," since they have no concept of the
history of either their language nor their own culture.
Clearly you have escaped the American destruction of the English
language -- although there is now a dictionary of the "American
Language," as distinct from English.
Next time I'll be in Toronto I'll invite you to your favorite pub and
we'll discuss . . . whatever and everything. As happens in any
European pub.
