I encountered the word "taphonomy" for the first time today. Basing a conjecture on its Greek roots, I thought it might refer to the law and customs pertaining to graves and burials.
My guess was wrong:

I don't mean any disrespect to paleontologists here when I say I wish my guess had been right. I suppose it's a consequence of my being less interested in the natural sciences than the social sciences and humanities.
