sneeze

Related to that last entry, the etymology of "sneeze" is pretty cool:

MW11 says it's from Middle English "snesen," alteration of "fnesen,"; related to Middle High German "pfnusen," to snort or sneeze, and to Greek "pnein," to breathe.

We've got a lot of "sn-" words in English, and some "pn-" words, but not so much with the "fn-".

Thanks, Will!
