I have a thing for words. I go through phases too. I love looking them up in a variety of dictionaries online and at home for as many definitions as possible. My favourite word for a while was privy. Here's one definition of it.
Privy - ( adjective ) 1. sharing in the knowledge of ( something secret or private ) 2. archaic, hidden or secret. ORIGIN: Middle English ( originally in the sense [ belonging to one's own private circle ] ) : from Old French prive ' private ' ( also used a s a noun meaning ' private place ' and ' familiar friend ' ) from Latin privatus ' withdrawn from public life '
