Thanks also for pointing out the word querulous! I don't think that the first tree that Treegle generates is so great. You have to click querulous a few times to get better trees. :)
Cool!! Thank you very much for sharing!! I actually never heard of Wordo until now. Do you work with Wordo? If so, wanta collaborate? :)
Yes I helped create Wordo. I am nerdy about words and definitions. I contribute to Wiktionary.
