When I was reading Jay Asher's 13 Reasons Why, I came across this sentence, "And the more we spoke, I knew why," and I was wondering what it might mean. Here is the context:
It seemed like you could know me. Like you could understand anything I told you. And the more we spoke, I knew why. The same things excited us. The same things concerned us. (p. 210)
The sentence in question reminds me of the structure "the+comparative, the+comparative" as in The more I know him, the more I like him, but the latter part of the sentence has no "the+comparative."
I agree with you about the similarity with correlative, or parallel comparative structures (the more... the more...). I'd say that your sentence is actually based on that structure.
The sentence, though unusual, sounds right to me. Although there is no correlativity, the "the more"-clause seems to render the same meaning of gradualness that parallel comparatives convey:
- The more we spoke, the more I realized how similar we were.
can be found to be similar to:
- As we continued to speak, I came to the realization of how similar we were.
- And the more we spoke, I knew why.
- And as we continued to speak, I knew why (it seemed like you could know me and understand anything I told you).
