The Role of Syntax in Language
This section is an introduction to syntax in language as far as it is relevant to the content of this book. It is not meant to be a rigorous discussion of linguistics. What I am describing is a simple orthodox view of the grammar of language. Some more complex models are discussed by linguists but these are beyond the scope of this description. This section is included for those readers who would like a brief overview without having to refer separately to a linguistics textbook. Those who would like to read more about the various linguistic theories should refer to the bibliography for references to linguistics books and to sites on the web covering linguistic topics.
Languages have rules. The rules of a language are called the grammar. The reason for these rules is that a person needs to be able to speak an indeterminately large number of sentences in a lifetime. The effort would be impossibly great if each sentence had to be learnt separately.
By learning the rules for connecting words it is possible to create an infinite number of sentences, all of which are meaningful to a person who knows the syntax. Thus it is possible to construct many sentences that the speaker has never heard before.
A finite number of rules facilitates an infinite number of sentences that can be simultaneously understood by both the speaker and the listener.
In order for this to work with any degree of success, the rules have to be precise and have to be consistently adhered to. These rules cover such things as: the way words are constructed; the way the endings of words are changed according to context (inflection); the classification of words into parts of speech (nouns, verbs, pronouns, etc.); the way parts of speech are connected together.
The rules of grammar do not have to be explicitly understood by the speaker of the language or the listener.
The majority of native speakers of a language will have no formal knowledge of the grammar of a language but are still capable of speaking the language grammatically to a great degree of accuracy. Native speakers of a language assimilate these rules subconsciously while the language is being learned as a child.
