DonS: What’s With Neo?

Don Sausser: I checked dictionaries on line for the word “neo” that gets attached to other words, i.e., “neo-con”, and above as (Joan Harman) used it, “neo-socialism” but I am yet to know what it means. One definition indicated it meant “new”. But as used so often on the blog, neo-con is used as a negative adjective for republican. As a high school graduate, I need help!

Question: Can anyone answer Don’s question? BTW, I know that Neo was the name of the main character in the “Matrix” trilogy. So let’s stick to “neo-” as it applies to labeling in politics and blogs.
