Earlier, a few people and I were sitting around and the claim was made that "pleaded" is not a word. So, I figured I would look "plead" up in the dictionary, and sure enough "pleaded" is an accepted form of "plead." Somehow, it being in the dictionary was not good enough for these people!
I just read here that "pleaded" is the preferred form, however WikiAnswers is definitely not how I am going to resolve this argument.
What I am looking for is some sort of peer reviewed explanation for why and how "pleaded" became/is a word (because...the dictionary isn't good enough...?)
Any help is greatly appreciated! Thank you!
