Word Classification and Sentence Structure

Word Classification

• Word classification is crucial for understanding sentence formation
• Words are grouped into classes based on their positioning in sentences
• Speakers' knowledge of a language includes its vocabulary (lexicon) and word classes (lexical categories)
• Lexical categories dictate a word's position in a sentence
• The traditional approach utilizes "parts of speech"
• A preliminary problem is identifying the different lexical categories and the words that belong in each category
• Traditional grammars outline the traditional view and its shortcomings in word categorization

Sentence Structure

• Sentences have a structure
• Sentences are infinitely numerous
• A grammar is required to calculate sentences
• This mental system (the computing system for human language) has elements and rules
• The contents are learned within the system of knowledge of human language

Phrase Structure Grammar

• One approach to modeling human language grammar is phrase structure grammar
• Phrase structure grammar doesn't describe whole sentences at once, instead breaking them into phrases
• By building phrases upon other phrases, sentences are ultimately created

PS Rule Basics

• Words can have more than one meaning
• Rules are given as an unconflated form (one rule for each phrasal possibility) or a conflated form
• Rules combine different but related phrasal possibilities into a single rule
• These rules dictate where words and phrases should go in a sentence

Infinity and Recursion

• Sentences are infinitely numerous, a key concept in linguistics
• This stems from the mathematical notion of recursion
• Rules (such as NP adjunction and VP adjunction) are recursive, capable of creating infinitely many different sentences
• This aspect of language creation is based on the structure of phrases

Modification and Structural Ambiguity

• Modifiers describe the nouns or phrases they are attached to
• Modifiers (often prepositional phrases) can modify their neighboring phrases
  • Their meanings and function are critical for interpreting complex sentences with multiple possible interpretations
  • A phrase, like a preposition phrase, can be an adjective or an adverbial
  • There is a modifier rule that determines what the modifiers in the sentence are modifying
• Recursion in sentences creates ambiguity, where a sequence of words can have multiple interpretations

Summary

• Sentence structure and modification are crucial aspects of grammar
• The infinite nature of language is explained by recursive grammar rules
