Wednesday's Word

I decided I needed my only little blogging niche. So I decided since I'm a prof writing and marketing major and becaue I want to increase my vocabulary, I shall try to help increase your's also. So here I introduce Wednesday's Word (and yes I know it's thursday now but I just thought of doing this and there isn't any vocab word realated to T that I could think of, so it's W,W) I'll be using m-w.com for my word source.

Today's word is:

nexus \NEK-sus\ (noun)
*1 : connection, link; also : a causal link
2 : a connected group or series
3 : center, focus

Example sentence:
When he was a jounalist, John wrote about the nexus between politicians and big business.

Wow, isn't this exciting?
