Verified words? - 2-nd edition

Here is the second occasional post of some of the "word verifications" which appeared when I commented on blogs; along with my impression of their meaning. Each one has been verified against dictionary.com and wikipedia. First edition was posted as Round 1. Today's words:

wikipedia - NOT a word, suggested "Nonsuch"
Lew's definition: non-su - A lawyer's nightmare.

ionate
dictionary.com - a REAL word, meaning "add ions to"
wikipedia - NOT a word, suggested "innate"
Lew's definition: i-o-nate - personalized IOU for Nathan

wikipedia - NOT a match, suggested "lester"
Lew's definition: les-tou - comment made reqularly on WKRP in Cincinati (old TV situation comedy)
