What are some new words someone could learn? like sophisticated words?

Avoid these word, and see what fills the void- not using these words will add to your sophistication:

Like
Actually
Duh
For real
Sure
Ya know
Man
Dude
Cool
Bro
Ho
sucks
Honestly, truthfully
and any four letter word, for sure!

Grab a dictionary. Every day, open it to a random page, and find 4 words you never heard before. You will learn hundreds before you know it.

Well it's always good to improve your vocabulary, good question! I'll leave these up to you to google...

- Disenfranchise

- Reestablish

- Cardinality

- Paradigm

- Transcendent

(There are about 20,000 more, but we'll stop there...!)

Reader's Digest used to (and I guess probably still does) have a section called "It Pays to Increase Your Word Power" which was designed to increase your vocabulary. I took a quick visit to their website, and apparently they now have an online version that you can play for free, although it does require registration. http://www.rd.com/realarcade/openRealArcade.do

In addition to what has already been mentioned, try Merriam-Webster's Word of the Day: http://www.m-w.com/cgi-bin/mwwod.pl
Maybe set it as your home page, and everyday you will be greeted with a new word to learn and build your vocabulary.

Try these:

Abtruse - Not easy to understand
Amity - Friendship
Anathema - Detested person or thing
Asinine - Stupid, idiotic
Assiduous - Hard working/Done with care
Auriferous - Containing gold

Just go through the dictionary page by page and you'll be amazed at how many words you've never heard of.
But then the difficult part is to try to get them into everyday conversations without looking 'asinine'

Dictionary.com will email you the word of the day - every day. You don't even have to look it up! Try to use it at least twice a day!

well were can i find like good words like that is there a good website besides dictionary.com?
