I've come across two latin-root duh's in the last day. And by this I mean that I've seen two separate word pairs in a new light that I don't know if I'll every be able to unsee.
Universal and University - Well I suddenly like the word 'university' a whole lot more than I used to. A place to be exposed to a universe of knowledge and ideas.
Secretary and Secret - Kinda puts a new light on those secret-keepers.
