Today’s word is: easily read in the title.
Cure showed up in the early fourteenth century as a noun and then later on as a verb. Originally, it meant care, like it does in its classical Latin form cura/curare, but it evolved from just “care for” to a medical sense. Cura can also be traced all the way back to the Proto Indo European kois-, be concerned. The word curate also comes from curare, by way of Medieval Latin, where it meant “to take care of souls”.
