Thanks for the response, Bruce.


1) The file you attached doesn't include the word "wolfing", nor "wolfin".
> I assume they need to be


The suffixes section accounts for this. Wolfing and wolfish both suppress
the ligature correctly.

I removed the comma separators, good catch. No difference, though.

Looks like I edited
/opt/context/tex/texmf-context/tex/context/patterns/mkxl/lang-en.llg
instead of the LMTX file. SMH.

I've now tried both files, lmtx and mkxl:

            suffixes = [[
                in
                in'
                in’
                ing
            ]],

Wolfish works fine, the ligature is suppressed as expected. Wolfing,
wolfin, and wolfin' aren't suppressed. I'd have thought that defining the
word "wolf" with a suffix of "ing" (and variations thereof) would suppress
ligatures at the suffix boundary?

Maybe that's not the case. If so, then it means having to define all the
*f-ing words (heh) a few times for the different suffixes (in', in’, and
ing), which seems to defeat the purpose of separating suffixes?

Help is appreciated.
