When I was in high school, I took a "vocabulary" class. One day, we did a lesson on jargon. The teacher asked us to get out a piece of paper and write down a list of words that we knew as a result of a hobby, interest or job that we had. While most people made lists of 6-8 words, I was able to make a list that ran all the way down the front of the page and onto the back. I included all sorts of words for pieces of plate armor (tassets, greaves, pauldrons, etc), I also included Charisma and Dexterity (which were new to me when I started playing at 10 years old), along with plenty of other words, many of which the teacher herself had never heard before.
As an aside, I also score extremely high on vocabulary sections of standardized tests. As a high school freshman my vocabulary was the equivalent of a sophomore in college (according to the Iowa standardized achievement test, anyway).
A rich vocabulary is something that I have received from gaming and so it’s also something that I try to give back. That's why a lot of the spells I publish have names like callithumpian discord, diaphanous shift, and Chromatic Coruscation.
I have an old unabridged Webster's dictionary, handed down to me from my mother's side of the family. It was published in the 1860s and is over 3,000 pages long. It has more cool words in it than I could ever imagine. That's where I get a lot of the words I use for spells in my published works.
In common speech I often use words like adjudicate, which results in a lot of strange looks from other people.
