I just finished reading James Swallow’s Day of the Vipers, the first book in the Terok Nor trilogy. While I can’t really recommend it, he did at least include some new Cardassian vocabulary. Most of it I’ll be working on over the next while (I’ve had an idea for a Cardassian geography post in the back of my mind for ages), but I can post a couple of things right now.
The Oralian Way features as a subplot throughout the book, and at one point, Swallow names the masks used in Oralian recitations as “Faces of the Fates.” This would be, in Kardasi, olla aThelaik (ohl-lah ah-Thay-lah-eek).
He also mentions seafruit as a sea cucumber-esque Cardassian food. Kaleanes (kah-lay-ah-nays) were probably named before people realised these things were actually alive. Whoops!
These two words, and probably a few more from the book, will be added to the next dictionary update.
Have a good one, all. <3
