  • DefinitionSyntax is the study of how sentences are structured or how words are combined with others to form sentences and in what order.

  • Traditional definitionEarly scholars often depended on the use of punctuation or a semantic criterion---the expression of a complete thought

  • Structuralist DefinitionAn independent linguistic form not included by some grammatical marks in any other linguistic form---it is not subordinated to a larger linguistic form. It is structurally independent linguistic form.

  • He didnt come until it was quite dark.Example

  • Constituent StructureTraditionally, sentences are assumed to be made of individual words in a linear direction.

  • Structuralists believe sentences are not composed of sequences of words in a simple linear, additive fashion. Instead, they are composed of hierarchies of constructions.

  • Immediate Constituent AnalysisIC Analysis is to simply divide a sentence into its constituent elements without at first knowing what these elements are.

  • The principle is that we take a sentence and cut it into two and then cut these parts into two and continue with this segmentation until we reach the smallest grammatical unit, the morphemes.

  • ConstituentAny linguistic form or group of linguistic forms that appears at the bottom of one of the lines

  • Immediate constituentThis refers to the two parts that are yielded after each cut. An immediate constituent can be further segmented until we obtain the smallest grammatical unit.

  • Ultimate ConstituentThe smallest grammatical unit obtained through segmentation

  • Transformational And Generative grammar

  • I.While IC analysis was capable of demonstrating some of the relationships in English sentence patterns, it provided no basis for analysis of the differences between sentences whose patterns were the same but the relationships different. Why Do We Need TG grammar

  • A:John is easy to please.B:John is eager to please.

    A:others could please John.B:John sought to please others.

  • 2. This problem comes into even sharper focus when ambiguous sentences are considered.Flying planes can be dangerous.In this sentence, the speaker may be afraid that an airplane will crash into his house or he may be afraid to take over the controls himself.

  • This sentence may refer to a time when the relatives come to visit or to a time when the speaker goes to see the relatives.Visiting relatives can be tiresome

  • 3. Similar problems must be dealt with in explaining synonymy---that is, sentences having the same meaning but different structures. John painted the picture. The picture was painted by John.

  • 4.Still other structures are recognized as similar by speakers of English. The girl has brown eyes.

    the girl's brown eyes

    the brown eyes of the girl

    the brown-eyed girl

  • Transformationalists hoped to meet these challenges:

    1) They proposed to describe the syntactic system shared by speakers of a natural language---English.2)They insist on the absolute precision of description.

  • 3)They insisted on simplicity of description. That is, all evaluation of proposed rules would be based on deciding which rules accounted for observable facts in the least complicated manner

  • 4) The ultimate goal of the grammar would be to account for the syntactic structure of all of the sentences possible in English.

  • Two concepts to UnderstandCompetence Vs performanceA set of rules that have been internalized in a persons mindAny actual utterances a speaker makes in a particular situation

  • Surface StructureSentences or phrases that are pronounced or written

  • Deep StructureThe structure that contains all the units and relationships that are necessary for interpreting the meaning of the sentence

  • Deep StructureThe terminal string that we get after we apply the PS rules

  • PS rule 1 S--->NP VP Ps rule 2 VP---> Vt NPPS rule 3 NP ---> Det N

  • The boy studied the book. S

    NP VP

    Det N Vt NP

    Det N

    Det N Vt Det N

  • Two Aspects of TG Grammar

    Transformational AspectGenerative AspectThis means that a grammar must generate all and only grammatical sentences of a languageChomsky proposes the idea of transformation which refers to a kind of process that transforms one sentence into another.

  • Components of a TGA Syntactic ComponentA Phonological componentA Semantic Component

  • A. Syntactic Componentthe basethe Transformational RulesThe base contains rules for the formation of deep structures

  • The BaseA set of phrase structure rulesThe lexicon:a full list of vocabulary itemsIt is concerned with the generation of deep structures

  • Phrase Structure RulesPS rule 1 S--->NP VP Ps rule 2 VP---> Vt NPPS rule 3 NP ---> Det NPS rule 4 Det --->the, a ,etcPS rule 5 N --->boy,man,etc.PS rule 6 V --->hit,sleep, etc.

  • The lexicon is a full list of vocabulary items. Attached to each item is information about its word class, and the syntactic slot into which it can be placed.Hit V, + [NP]Sleep V, -[NP]

  • These are the restrictions on the type of noun that can be selected with each verb.*The man hit sincerity.Selectional restrictions can prevent many figurative usagesSelectional restrictions

  • In her anger, she absolutely screamed at him.Absolutely

    *In her anger, she absolutely spoke to him.

  • 1.The tired farm-worker plodded home.2.The horse ambled slowly.3.They tramped forty miles in search of work.4.The pompous official strutted arrogantly.5.Couples strolled by lazily.6.He sauntered through the town enjoying the sunshine.7.He strode out vigorously and angrily.8.He walked because the bus had gone.

  • To yearn for affection (long for with tender feeling, affection,etc.)To crave for a drug( ask earnestly for; have a strong desire for)
