Students must learn all the rules of sentence formation to speak and write English. An Important component of language is syntax which is a key in responding to this myth.
Syntax is the structure of words and phrases to make a sentence in any language.
Knowing a language means one can create an infinite number of sentences never heard before, never known before. These are just prototypes of sentence structures. In this equation, S means structure, NP equals noun phrase, and VP equals verb phrase. Phrase structures do not describe English or any human language, but are used for speculating on what is believed to be going on in a sentence. To break this down even further, there are lexical items which attach to nodes.
