That's nuts, looking at 19 dictionaries, probably 2/3 of them have the first definition of smitten one I'd never heard.
I'd only seen, and used, smitten as meaning, "to impress favorably; charm; enamor", or, "having suddenly started to like or love something or someone very much".
Until my last post here, I'd never made the connection between smite and smitten. Learn something new every day.
