Fun with words.

I was was looking for something in the dictionary this morning when I ran across this definition:

diakinesis: the final stage of meiotic prophase marked by contraction of the bivalents.

I think it's a term from microbiology, but don't quote me. Haven't the faintest idea what the definition means let alone the word. "College dictionaries" are full of words like this from medicine, genetics, biology, linguistics, law and so on for good reason. But still it's funny and a little bothersome to run across "words" that are really just professional jargon and not at all useful outside of their special field. Remember how you spent weeks or months learning terms like this for one class or another? How much do you remember now?
