displaying our own erudtion, like a peacock attracting a mate

Today's Word of the Day is:

apposite \AP-uh-zit\, adjective:
Being of striking appropriateness and relevance; very applicable; apt.

I rather enjoyed the sample usage of the word:

Suppose, for example, that in a theoretical physics seminar we were to explain a very technical concept in quantum field theory by comparing it to the concept of aporia in Derridean literary theory. Our audience of physicists would wonder, quite reasonably, what is the goal of such a metaphor--whether or not it is apposite--apart from displaying our own erudition.
