Rollbacks to list of English words ending in "-sis
Fragment of a discussion from User talk:Rua
It's not a list of words ending in "-sis", but a list of words suffixed with "-sis". The difference is that the former is merely a surface feature of a word, while the latter is about the origin of the word. Such categories should never be added by hand, but always by an etymology template such as {{affix}}.
