From the last hundred pages or so of The Life and Opinions of Tristram Shandy, Gentleman:

ratiocination: the process of logical reasoning.
aposiopetic: (aposiopesis) breaking off a sentence in the middle, as if unable to proceed
parallelogramical: parallelogram-shaped (clearly; I just liked the word).
radix: the base of a numerical system, or the root of a plant (interesting).
jactitation: a boast that causes harm to another, also extreme restlessness in bed?

farthingal: hoops used to expand women’s skirts at the time of the book.
