[Gertrude] Stein was passionate about grammar. "I really do not know that anything has ever been more exciting than diagramming sentences," Stein said. She found parsing sentences to be "completely exciting and completely completing." I completely agree. One line for subject, two for predicate, three for object. Wiggly lines for something. My favourites were the triangular brackets—I just can't remember what they were for. The exercise taught me about the construction of language as a system of coding. Stein probably didn't see it that way, of course; for her, it seems to have had something to do with finding the underlying logic of language, its inner mechanics, and with working out how language could be reconfigured to suggest new ways of thinking. Stein seems to have instinctively understood that language is an invented thing, floating free of the world, and that we are at liberty to bend it to our impulses and needs.If, like mine, your heart went pitty-pat at the phrase "diagramming sentences," then you probably need to read the entire article this passage is excerpted from. It's one of the best essays I've read in a while, and it actually got me hankering to read some more of Stein's work. Which, if you've read her, you'll know is saying something.
