Seven of the following eight 12-letter words have something in common and one does not. Which is the odd one out?

ambidextrous bankruptcies demographics harmoniously housewarming lexicography malnourished unforgivably

'Harmoniously', because all the other words are constructed from at least 2 different parts, e.g ambi/dextrous, mal/nourished, un/forgivably.
