At the Public Domain Review, Hunter Dukes writes about “American Grammar: Diagraming Sentences in the 19th Century”:
More than a century before Noam Chomsky popularized the idea of a universal grammar, linguists in the United States began diagramming sentences in an attempt to visualize the complex structure — of seemingly divine origins — at their mother tongue’s core.Dukes provides many examples of these efforts (with links to the books they’re drawn from). Here is a fairly tame diagram of a syntax tree, from Charles Gauss and B. T. Hodge’s A Comprehensive English Grammar (1890):
[Click for a larger tree, which you must imagine as standing upright.]
Alonzo Reed and Brainerd Kellog’s streamlined (and soil-less, and bark-less) approach to diagramming sentences — still taught in some schools — is an earlier invention, introduced in Higher Lessons in English (1877). I wonder why anyone would have opted for the ornateness of Gauss–Hodge instead.
Thanks, Steven, for letting me know about this PDR post.
