definition in a box

[afe]

Hello, I was wondering if it is possible to have a certain word when hovered a box appears, and the box contains text. In my case, the text would be the definition of the word. Please and thank you!:)

Look through the above index for a script to suite your needs; or you can search google for a tooltip onmouseover script.

Hope this helps.
