People bitch like whores about our semi-extensive vocabulary here; then again, people bitch like whores about anything, because they think it makes them seem smart, important, etc.
The ANUS(tm) vocabulary would have been considered normal or even a bit vernacular 200 years ago. It would not have been considered challenging. If you want to know why we don't wimp out... that's one big reason. Never say "yo, go ahead" to entropy.
Here's one good resource for building your vocabulary the easy way: A Word a Day (AWAD) from Wordsmith.org.
For over a decade, this list has mailed out a new word every day, most of them useful in conversation....http://wordsmith.org/awad/
I recommend this to anyone wanting to build up a vocabulary.
