2012 Word of the Year

My 2012 word of the year is "pivot". My earliest recollection of encountering this word was in primary school science lessons mumblety-mumble years ago. The topic, as I recall, was simple machines and "pivot" was used synonymously with "fulcrum". And it was invariably a noun. This year I've heard the word "pivot" being used in various contexts, including tech entrepreneurship and politics. And always as a verb.
