I thought I should share two resources dear to my study of Latin. These are twin tools I use when searching for English words with Latin roots, or Latin words with English derivatives.
Certainly, I profit immensely from becoming tongue-tied between the two languages—if that makes sense.
There’s some danger here. Certain common Latin words, like prōspiciō, have comparatively rare English derivatives like prospicient. Naturally, after a few weeks of reading Cicero, prospicient feels like an ordinary word because you encounter its root relative so often in the text. It’s not, and I get looks for letting it loose in casual conversation. Beware.
For finding English derivatives, I use this Wikipedia page.

Now, with a simple [ command/control+f ], it’s easy to search for either Latin roots or English derivatives.
However, for finding Latin roots of English words, I prefer this handy etymology dictionary, which reveals the precise history of many English words.
Neither of these tools is nearly comprehensive—so if there’s a particular world you’re interested in, a simple Google search might work. That said, if the words you’re after aren’t on either of these sites, (in my experience) they probably aren’t on Google, either.
If readers have any additional sites to suggest, I’m all ears!
Happy Hunting!
