Consider the rhyme of

womb

with

tomb

It has the delicious property that these two words describe, if you will, the two chambers from which we enter this life and through which we leave it. Not only do the two words rhyme on the ear, in other words, they can also be said to rhyme in meaning.

Meditation: if you were wearing headphones, and these two words were spoken, what would the stereophony of their meanings be?
