What is phrase structure grammar?
Phrase structure grammar is a type of generative grammar in which constituent structures are represented by phrase structure rules or rewrite rules. Some of the different versions of phrase structure grammar (including head-driven phrase structure grammar) are considered in examples and observations below.
What is a phrase structure in linguistics?
Phrase structure rules specify the well-formed structures of a language pre cisely and concisely. They express the regularities of the language and make explicit a speaker’s knowledge of the order of words and the grouping of words into syntactic categories.
What are the components of phrase structure?

What do you understand by phrase structure grammar explain its limitation?
A phrase structure grammar is essentially a grammar of segmentation and categorization, it is a taxonomic model – a grammar of lists, an inventory of elements, and a class of sequences of elements. Although it is very strong in giving a structural description of the language, yet it is deficient in generative capacity.

What is the importance of sentence structure grammar in linguistics?
They play a key role in computational linguistics and Natural Language Processing. Their relevance for the investigation of human language processing is studied in Psycholinguistics. Phrase structure grammars provide a formal notation for the analysis of the internal structure of sentences.
