Most of the stuff on verb.ly comes from the verb.ly idea engine (my brain).
But not everything. In particular, many of the things in the Literature Collection and the Philosophy Collection are quotes.
Where something comes from another brain, I clear it copyright-wise.
Some recent collections near the bottom of the homepage with people's names on them – I'm currently contacting those people (snail mail recorded delivery). If you are one of those people, I'm at firstname.lastname@example.org (this paragraph added 22 July 2019)
Likewise, if you want to use something from verb.ly, just ask for permission first – email email@example.com
