Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components... the syntactic component of a grammar must specify, for each sentence, a deep structure that determines its semantic interpretation and a surface structure that determines its phonetic interpretation. The first of these is interpreted by the semantic component; the second, by the phonological component.
Syntax is the study of the principles and processes by which sentences are constructed in particular languages. Syntactic investigation of a given language has as its goal the construction of a grammar that can be viewed as a device of some sort for producing the sentences of the language under analysis.
I looked out the window at walls of moonlit cloud rising beside us as though we we were at the bottom of some, gray and ivory canyon, hung above the moon-smashed sea... But, with whatever hindsight, I suppose the reason that I want to close on a consideration of these words is that the moon-solid progress through high, drifting cumulus is - read them again - at the very opposite of what we perceive on a liquid's tilting and untilting top, and so becomes the other privileged pole among the images of this study, this essay, this memoir. Or perhaps, as it is only a clause whose syntactic place has been questioned by my own unscholarly researches, I merely want to fix it before it vanishes like water, like light, like the play between them we only suggest, but never master, with the word motion.
