Gotta Work on My Vocabulary

I'm taking a class that surveys the Biblical books of Judges through the Poets. One of the texts I am using is Bruce K. Waltke's An Old Testament Theology. It's a great book that outlines the themes and structures of the books of the Old Testament. Dr. Waltke (who is teaching my class) does have an amazing vocabulary. I mean, it's sick. Here's a list of words I had to look up just in the one chapter I read tonight:
regnal
fecund
peripeteia
irruption
onomastic
redivivus
nugatory
majordomo
surd
usufurcts
My dictionary didn't even have all these. I had to look some of them up on the internet. Crazy. I'll give bonus points to anyone who can define these without a dictionary.
