I think it’s an excellent list. I knew most, but the following stumped me. I list the he words followed by my guesses at their meanings:
abjure — to withhold judgment?
abstemious — should know it but I’m blanking
bowdlerize — to debase? to give a lowbrow meaning to something fairly lofty?
fiduciary — something to do with money but I’m not sure what
evanescent — should know this one too. New, on the rise, in early stages?
lugubrious — smarmily charming?
obsequious — another one I should know. Coy, indirect?
moiety — have no idea
Bowdlerize -- after some jerk named Bowdler, who advocated -- and for a time was succesful at -- substituting ''inoffensive'' words for ''ribald or suggestive'' ones in a text. Egomaniacally, the first author's works he attempted to ruin was Shakespeare. An early advocate of what we now call 'political correctness', except he was principally concerned with 'moral' 'correctness', according to his standards.
fiduciary -- as a noun, describing a person in a position of legally binding trust, as for instance the executor of a will, or an attorney charged with keeping funds intact for a trial or other purposes. as an adjective, descriptive of a fiduciary person.
moiety -- a part of, typically an indeterminate part of. rarely, used as a synonym for 'half'. ''He had merely a moiety of knowledge about the theatre, not the totality he supposed'' -- Goldsmith.
Sad or depressed: Droopy the Dog had a lugubrious expression.
obsequious — another one I should know. Coy, indirect?
Brown nosing behavior: My sycophants must always be obsequious.
