This time we (and by we I mean me) are looking at dread.
Dread first showed up in the late twelfth century as a shortened version of the Old English word adraedan, which itself was a shorter version of ondraedan, advise against. The prefix on- means against, while raedan is advise. Oh yeah. Raedan is also the origin word for read, which had a variety of meanings, including advise, discuss, guide, explain and, of course, read. Combined with the against, the word becomes “advise against”, which is a good definition for something to dread.
This might be the first time I’ve ever found two words similar in spelling that are connected in a way that makes sense.
