I have to agree with William, you're not being very "coherent" or specific enough when it comes to a few things;
- What is being asked (expected) of you by the teacher?
- What is your vision; what do you hope to get from the experience and too, what do you hope to leave the participants with?
- What kind of magic are you most qualified in when it comes to experience & skill?
- Are you trying to reveal peculiarities -- deception -- within language (such as how lawyers and sales people are able to twist words)?
There are simply too many variables and you really have confused what it is you wish to make happen.
If I were to address a Language-focus class on the idea of "Illusions (deception)" within language I think I'd be looking at source material that deals specifically with this concept, such as the WONDER WORDS series. While it was penned to help performers develop better scripts it likewise deals with NLP type correlations and as such, you will find perspectives on how stating things one way can mean something entirely different than what the person hearing it would interpret it as meaning. You can do the same with punctuation tricks, showing how a comma in the right point of a sentence totally transform the emphases. Even the use of color and shape (written description or spoken) can lead a person towards a specific idea by way of subliminal programming, anchoring, pacing & leading, etc.
This is a HUGE area that's open to a plethora of effects IF you are experienced and skilled enough to pull them off. You have to be exceptionally well rehearsed, have solid management skills with your audience & helpers, and know how to shift gears when things don't happen as they're "supposed to"... language manipulation and forces are some of the more difficult and least sure-fire modes in magic/mentalism, so don't think for a second that someone is going to name a "Rose" just because you told them to name the first flower that comes to mind.
I believe you said that you have time (a few months?) to pull this together. . . if so, then you haven't time to waste should you wish to move along this particular corridor. I'm biased in that we're talking about Mentalism styled work that, when framed and presented properly, can be quite devastating; a solid routine based on this sort of stuff could easily be a career launcher (ask Joel Bauer, it's right up his alley).
If you are planning to take a more traditional magic approach or worse, loads of card tricks, I really can't see it working or. . . I should say. . . I can't see it being as psychologically effective and viable. But let's look at your thinking and where you believe things should go and build from there. . . that is, if I've not scared you off.
