Phrase Structure Rules
Phrase-structure rules are a way to describe a given language's syntax and are closely associated with the early stages of Transformational Grammar. They are used to break down a natural language sentence into its constituent parts (also known as syntactic categories) namely phrasal categories and lexical categories (aka parts of speech). A grammar that uses phrase structure rules is a type of phrase structure grammar - except in computer science, where it is known as just a grammar, usually context-free. Phrase structure rules as they are commonly employed operate according to the constituency relation and a grammar that employs phrase structures rules is therefore a constituency grammar and as such, it stands in contrast to dependency grammars, which are based on the dependency relation.

Famous quotes containing the words phrase, structure and/or rules:
“Many people will say to working mothers, in effect, “I don’t think you can have it all.” The phrase for “have it all” is code for “have your cake and eat it too.” What these people really mean is that achievement in the workplace has always come at a price—usually a significant personal price; conversely, women who stayed home with their children were seen as having sacrificed a great deal of their own ambition for their families.”
—Anne C. Weisberg (20th century)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“... cooking is just like religion. Rules don’t no more make a cook than sermons make a saint.”
—Anonymous, U.S. cook. As quoted in I Dream a World, by Leah Chase, who was quoted in turn by Brian Lanker (1989)
