One website I return to time and time again is etymonline.com, the one stop shop for the root origins of words. I don’t know what I would do without it!
The other day, I also found Read The Plaque based on another thread, a map with transcriptions of all the plaques in the world. I also love Pun Generator so I can automate my wit and Make My Drive Fun, a somewhat buggy mapping system that finds all the roadside attractions between two locations.
It made me wonder - what other websites are out there that are single purpose, yet incredibly useful resources that help you better understand the world? I’d love to know your secret sites!
