[Matt Q]

Ah, Ralph, I must protest.

Firstly, and possibly a little pedantically, 'kipper' is not a synonym for 'asleep'. A kipper (in this sense) is one who tends to kip, which is not equivalent in meaning to 'asleep'. Though I guess we might conclude that since Mark is asleep in a cafe he is more prone to kipping than most and is a kipper.

Secondly, let's say it is a synonym, then I guess what I have is an 'identity' conceptual rhyme.

Which is another way of saying that, if you follow Zapruder's definition, that the two words must be associated, it's hard to argue that synonyms aren't associated. They point to the same concept no? And as you say in your thread, conceptual rhyme [is] "also called “thought rhyme” or “parallelism,” it was common to the Hebrew poetry". And I'd say that this:

for he founded it upon the seas
and established it upon the waters

this is parallelism. And the words echoed are synonyms. Just as much as this is parallelism:

Are your wonders known in the place of darkness,
or your righteous deeds in the land of oblivion?

where the conceptual rhyme is less close.
