Query: a very important work now in kindle

One of the most important works of Chomsky's. It is preceded by experimental modelling of linguistic knowledge based on rewriting rules and the resulting conclusion of the need for transformations and is followed by new innovating ideas on restricting the power of transformations. We already see the deep thinking that went into the development of the next stage. He discusses the idea of 'singulary transformations' which the individual transformations were, then, composed of and which later developed into Move-alpha, Delete-alpha, etc. He argues very persuasively for a separate 'lexicon' and the kind of information we should expect to find there. Overall, it is rich with seeds that later developed into the ideas comprising the 'principles and parameters' theory. And most importantly, it gives the shrewd and disciplined argumentation, which became a standard of Chomsky's later works and generative grammar in general.
