My testing with Plain TeX shows that the original patterns do hyphenate
"democrat" as "demo-crat". It's "democrats" that they don't hyphenate at
all.

Oh, I was pointing to the full TUGboat exception list, the file that Werner
generated based on your work.

I concur with the thanks, but would like to point out that the

I think there's been a misunderstanding here. My suggestion was that we
remove the patterns Gerard Kuiken had added to the original Knuth pattern
list, because they are incorrectly generated and expand the exception list
they currently have (which are the original list from Knuth) to include
everything from the TUGboat list. That's actually what I decided to do for
Android, because there didn't seem to be any reasonable alternative short
of trying to get my hands on a comprehensive English word list and trying
to regenerated the expanded patterns myself.

I'd be looking forward to the publication of the new list.
