Compounds and [[Template:affix]]
Fragment of a discussion from User talk:Kephir
To find any possible misdetections, you would have to copy the detection code to the {{compound}} function in the module, and track any entries for which the detection does not result in "yes this is a compound".
Here it is: Special:Whatlinkshere/Template:tracking/compound/looks like confix, Special:Whatlinkshere/Template:tracking/compound/one whole word. It seems there are not so many of them, but I guess we have to wait until the job queue goes through it all to be sure.
