It's probably possible but your post is unclear. If the question was, "What is the airspeed velocity of an unladen swallow?", what do you want to happen?
I want it to search that questions to see if a word in the questions is in the word definition table and if it is make that word a link. So if "airspeed" is in the word definition table it would search question and see the airspeed is htere and make just that word a link.
Something like this:
select word, definition
where word in (<cfqueryparam value="#yourquestion#" list ="yes" separator = " ">)
should get you started. You'll probably have to do something about capital letters.
