Word Nerds: Yes, that is a word…
Your search for that precise descriptor has ended with this batch of discovered words. I must admit I am familiar with “twaddle” and have come across “quidnunc” no doubt due to those old English mystery novels from the forties that I favor.
kyoodle: to bark or yelp noisily or foolishly
gloze: to explain away
twaddle: silly, tedious talk or writing
otiose: serving no practical purpose or result
recondite: relating to, or dealing with something little known or obscure
parlous: full of danger or uncertainty
drouk: to drench
elucubrate: to produce (something) by long and intensive effort
opprobrium: harsh criticism or censure
quidnunc: person who seeks to know all the latest news or gossip
I need to find a way to work “kyoodle” into a conversation.

Oh, dear, I fear I gloze far too often, and may therefore be percieved as a tedious twaddler!
Never would that be a consideration and never would you be one who kyoodles needlessly into the neighborhood of blogdom.
I’m glad I’m not a quidnunc.
It’s a fun word to come across in a novel,
Yes!
