Poetry; etymologically from poiein, ‘to make’. Poetry makes and since it makes with words and words are generally taken to mean something, poetry may even be regarded as the production of meaning.
But any given poem is likely to mean different things to different people at different times. Therefore, if poetry produces meaning, it is in fact producing an excess of meaning.
In other words, no poem means one thing and if it means anything, this thing is the fact that it means more than its meaning and, one may even venture to say, primarily means this surplus.
Poetry makes the meaning that exceeds itself and is itself this excess.
