I remember watching Sesame Street back in the day and there would be these special words, letters and numbers "of-the-day." Along that rich tradition of early childhood education, I hope to promote that same fervor of excitement towards vocabulary.
So . . . the word for the day is "antidisestablishmentarianism." Its original meaning is derived from "establishment" which referred to the Church of England (church & state together - or the principle of a state church). I always thought that the "establishment" was something else (so my gay, middle age, white male, feminist humanities professor from San Francisco City College would often "drop").
