Design practice

Design is about doing. Letter, 
Word, Sentence, Paragraph.

New brief.
A new typography book being published by HOW books is now accepting submissions.
I am required to submit a series of three "TYPOGRAPHIC" posters 
that focus on the word "OPPOSITES"


Where to start.
Well, the first step is defining the word "Opposite" and 
see what I can play around with. This was what I got from 
the Oxford english Dictionary-


Adjective
1 [attributive] situated on the other or further side when seen from a specified or 
implicit viewpoint; facing: a crowd gathered on the opposite side of the street
(of angles) between opposite sides of the intersection of two lines.
Botany(of leaves or shoots) arising in pairs at the same level on opposite sides of the stem.
2 completely different; of a contrary kind:
a word that is opposite in meaning to another
currents flowing in opposite directions
[attributive] being the other of a contrasted pair:
the opposite ends of the price range


So it's quite clear that I need to design something that communicates 
two completely different things but in one poster.
