More words I like from the Wordsmith Word-a-Day Mailing List
Star Chamber
A court or group marked by arbitrary, oppressive, and secretive procedures.
Locum
A person filling in for another, especially for a doctor or clergyman.
Steenth
1. Latest in an indefinitely long sequence. 2. One sixteenth.
[Alteration of the word sixteenth.]
Also, the Wordsmith included this:
Notes: The formation of the word “steenth” from “sixteenth” took place through a process called aphesis (from Greek, literally “a letting go”). Aphesis is when an unstressed sound from the beginning of a word get lost over time.
Some other examples are: “cute” from “acute” “‘tis” from “it is” “gypsy” from “Egyptian”, from the belief that Gypsies came from Egypt (they actually came from India).
Trichotillomania
A compulsion to pull out one’s hair.
[From Greek tricho- (hair) + tillein (to pluck, pull out) + -mania (excessive enthusiasm or craze).]
paper tiger
One who is outwardly strong and powerful but is in fact powerless and ineffectual.
