A Book of Words

words I didn't know before,
words that are precise or concise beyond more familiar alternatives,
words that seem useless, but are apparently in use,
words with a surprising or appropriate juxtaposition of senses,
words which have been unfairly left out of crossword puzzles,
words that preserve or transform a root sense,
words whose meaning should have been obvious,
words that come in odd groups,
words intriguing in themselves.

(Definitions for each set of words are available from the question-mark link.)
