Cliquiness, Intransigence, Conforaneous, Colloquy, Grandiloquent

• cliquiness - the state, quality or condition of being cliquey - an exclusive circle of people with a common purpose
• intransigence - the trait of being intransigent; stubbornly refusing to compromise
• conforaneous - of the marketplace or court
• colloquy - a formal conversation
• grandiloquent - given to using language in a showy way by using an excessive number of difficult words to impress others

Not from anything in particular. I think one is from "The Bicentennial Man and Other Stories" by Isaac Asimov. Most were the rabbit hole of searching for useful words and self reflection.
