I want to use words that may need explanation. I would like to create the definition once and when I use the word in a post, to make it look like a link, but just have the definition show up if the viewer hovers over that link. I have not figured out how to do it, and I don't know what to call it to search for it in a forum. I tried it as a link, but it didn't work.
The blog I need help with is livingwaters2011.wordpress.com.
