Thanks for passing on the examples. Still, I didn't really see much of
Eliot in the punning. Most of these I saw as word play, son/sun is an
exception. It depends on the definition of pun and I think of this
being the use of a word with two meanings, thus my example of Leman.
In The Waste Land I see Eliot using punning in a matter like the
examples you gave in these lines:
423 I sat upon the shore
424 Fishing, with the arid plain behind me
430 These fragments I have shored against my ruins
In Seven Types of Ambiguity Empson uses Eliot as an example in his
second category of ambiguity. ("In second-type amiguities two or more
alternative meanings are fully resolved into one.") Empson gives
examples for Eliot use of what is "poured" in the Belladonna section
of Part II. Another, similar, example can be found in the Fire
Sermon. Here I've added a bit to make things a bit more obvious.
