Syntax Notes

Syntax involves breaking down sentences to understand the relationships between words, including how words form phrases and how phrases form clauses.
Constituent tests help determine word classes by asking questions:
- What/who is doing it? = subject noun (identifies the actor in the sentence)
- What/who is it being done to? = object noun (identifies the receiver of the action)
- What is it doing? = verb (identifies the action)
- What is it like? = adjective (describes a noun)
- What is it doing it like? = adverb (describes a verb, adjective, or another adverb)
- Where is it/where is it going to? = preposition (indicates location or direction)

Syntax: From the Greek "Syntaxis," meaning arrangement; the study of how words and phrases are arranged to form sentences.
Focuses on the ordering of words and their grouping into phrases and larger units called clauses, and how these structures convey meaning.

Sentences can be segmented into clauses to understand their structure, revealing how different parts of the sentence relate to each other.
Examples of sentence segmentation:
- "Students Cook & Serve Grandparents"- [[students] [cook and serve] [grandparents]]
  - Illustrates potential ambiguity: do the students cook the grandparents?
  - [[students] [[cook] [and] [serve] [grandparents]]]
  - Clarifies the intended meaning: students cook and then serve the grandparents.

Word - word classes (parts of speech such as nouns, verbs, adjectives)
Phrase - how word classes group together to form phrase classes (e.g., noun phrase, verb phrase)
Clause - A group of words, consisting of a subject and a finite form of a verb joined by conjunctives; can be independent or dependent.
Sentence - whole utterances; a set of words that is complete in itself, typically containing a subject and predicate, conveying a statement, question, exclamation, or command, and consisting of a main clause and sometimes one or more subordinate clauses.

Every complete sentence contains a subject and a predicate; these are essential components.
The subject is what (or whom) the sentence is about; it performs the action or is described.
The predicate tells something about the subject and contains the verb; it describes what the subject does or is.
Examples:
- David plays the piano
  - Subject: David
  - Predicate: plays the piano
- The police interviewed all the witnesses
  - Subject: The police
  - Predicate: interviewed all the witnesses

A phrase is a syntactic unit containing more than one word but lacks the subject-predicate relationship, differing from a clause.
It contains a headword, which is the most important word, determining the nature of the phrase.
Other elements specify, modify, or complete the headword, adding detail and context.
Elements can be placed before (specifiers, premodifiers) or after (postmodifiers, complements) the headword, influencing its meaning.
The type of phrase is determined by the headword; the headword dictates whether it is a noun phrase, verb phrase, etc.

A syntactic unit consisting of a noun and associated words; functions as a subject, object, or complement in a sentence.
Structure: Specifier + Prenominal modifiers + Head noun + Postnominal modifiers
- Specifier: Determines the noun (e.g., articles, possessives)
- Prenominal modifiers: Describe the noun (e.g., adjectives)
- Head noun: The main noun in the phrase
- Postnominal modifiers: Provide additional information (e.g., prepositional phrases, relative clauses)
Example: The lively little painting of Paris which I bought last year.
- The: Specifier
- lively little: Prenominal modifiers
- painting: Head Noun
- of Paris which I bought last year: Postnominal modifiers

A syntactic unit consisting of a verb and associated words functioning as auxiliaries, modifiers, and complements; expresses action or state of being.
Structure: Auxiliary + Pre-verb modifier + Verb head + Complement(s) + Postmodifier
- Auxiliary: Helps the verb (e.g., has, have, had)
- Pre-verb modifier: Modifies the verb (e.g., adverbs)
- Verb head: The main verb in the phrase
- Complement(s): Completes the verb's meaning (e.g., direct object, indirect object)
- Postmodifier: Adds extra information (e.g., adverbial phrases)
Example: has never written a letter to his aunt when he lived in Rome.
- has: Auxiliary
- never: Pre-verb modifier
- written: Verb head
- a letter: Direct object
- to his aunt: Indirect object
- when he lived in Rome: Postmodifier

A syntactic unit consisting of an adjective and associated words; modifies nouns or pronouns.
Structure: Premodifier + Adjective head + Complement
- Premodifier: Intensifies or modifies the adjective (e.g., quite, very)
- Adjective head: The main adjective
- Complement: Completes the adjective's meaning (e.g., prepositional phrase)
Example: quite fond of chocolate
- quite: Premodifier
- fond: Adjective head
- of chocolate: Complement

A syntactic unit consisting of an adverb and associated words; modifies verbs, adjectives, or other adverbs.
Structure: Premodifier + Adverb head
- Premodifier: Intensifies or modifies the adverb (e.g., very, quite)
- Adverb head: The main adverb
Examples:
- very well
- unexpectedly reluctantly

A syntactic unit consisting of a preposition and a word/word group that completes its meaning; often functions as an adjective or adverb.
Structure: Premodifier + Preposition head + Object of the preposition
- Premodifier: Modifies the preposition (e.g., right, straight)
- Preposition head: The main preposition (e.g., in, on, at)
- Object of the preposition: Noun phrase or pronoun that the preposition relates to
Example: right into the centre
- right: Premodifier
- into: Preposition Head
- the centre: Object of the preposition

Syntax trees are used to visually represent the structure of sentences, showing relationships between words and phrases.
Start by dividing the sentence into Subject (NP) and Predicate (VP); this is the first level of analysis.
Break down phrases into their constituents, showing how each phrase is composed.
