Pronounced: uh-rek-suh-JEN-ik, adj
Notes: I saw “rex” in the word and thought it may have to do with kings or royalty (I was wrong; besides, this word does not come from Latin)
The word pridian means “of or relating to a previous day or to yesterday; also: former”.
Background / Comments
For such a useful word, it isn’t used much at all. It comes from Latin pri- (before) and dies (day). It’s really a pity that such a useful word never really caught on.
While it was certainly used in 1840, and seems to have been around for a few hundred years, the actual date of the first usage is hard to determine.
