Is there any where that I can download the database/dictionary for word families? For example one line of it will have something like this:

Pellucid, pellucidity, pellucidly, pellucidness

A top google search gives me the Word Family Framework of British Council. But it only contains popular words. I also have tried all the links in Is there an online sample sentence database or search engine? question, but they don't give me what I need.

    @Ooker ~ good point, I didn't even look through it haha. How about this one: enroots.neocities.org Has 28000 word families supposedly – user180089 Jul 20 '16 at 18:07

    @Ooker Yes, aspell is a spell checker but it is complex enough to print out things. You can get a word list from it, it has a list of suffixes, so I'm guessing that there might be a way to print off roots possibly and maybe the legal suffixes for each root, I don't know, just a suggestion to research. As to 'leal' I probably meant 'all'. – Mitch Jul 21 '16 at 15:10

    I’m voting to close this question because it is a question suited to ELU.Meta rather than ELU. And showing instances of other questions going against site policy isn't respecting the site. – Edwin Ashworth Oct 19 '20 at 18:23

This page has a list of ~28,000 word families: http://enroots.neocities.org/

"This list is a combination of lists 1 to 25, 32 and 33 of the BNC/COCA word family lists by Paul Nation. Nonsense words (lists 26 to 30), proper nouns (list 31) and abbreviations (list 34) were not included."

If you'd like all 34 lists then check out the links at the bottom of this page: http://www.laurenceanthony.net/software/antwordprofiler/

specifically the link: "BNC/COCA family lists + extras (Version 2.00)"
