2011-12 LINGUA INGLESE 1 modulo A/BIntroduction to English Linguisticsprof. Hugo Bowles Lesson 8 Syntax 1
Syntactic analysis – building a tree • For your exam you need to be able to analyse a simple sentence into its component parts and illustrate it as a tree structure • The aim of this lesson is to get you from words to sentences • So we start with words and build from there
Sentences • Sentences, like the morphology of individual words, can be analysed using trees to illustrate their phrase structure • In order to be able to analyse a sentence you need to understand the main grammatical categories
Grammatical categories • Nouns (N) dog, cat, apple, park etc. • Determiners (Det.) a, the, this, that etc. • Verbs (V) walk, come, go • Adjectives (A) big, black, hairy etc. • Adverbs (Adv) quickly, slowly etc. • Pronouns (PRO) he, she etc. • Prepositions (P) in, on, under, over etc.
From words to categories • Words have to be attached to their grammatical category dog the walks hairy park quickly in the N Det V A N Adv P Det
… and then they have to be put in order the hairy dog walks quickly in the park Det A N V Adv P Det N
The base of the tree words and categories are the base of the tree the hairy dog walks quickly in the park Det A N V Adv P Det N
From categories to phrases to sentences • words are connected to categories • categories combine to form phrases • phrases combine to form sentences What kind of phrases are there?
Types of phrase • Noun phrase (NP) • Verb phrase (VP) • Prepositional phrase (PP) • Adverb phrase (AdvP) • Adjective Phrase (AP)
Phrases • Each sentence contains a subject and a predicate the hairy dog walks quickly in the park • Syntactically these correspond to: a and a the hairy dog walks quickly in the park noun phrase verb phrase
The top of the tree • So the tree for any sentence (S) should start like this: • This means that every sentence is made up of a noun phrase and a verb phrase S NP VP
The base of the tree words and categories are the base of the tree the hairy dog walks quickly in the park Det A N V Adv P Det N
Connecting the tree • What we need to do is to connect: the structure at the top of the tree TO the words of the sentence at the bottom of the tree the hairy dog walks quickly in the park S NP VP Det A N V Adv P Det N
Connecting top and base • You need to start at the base of the tree and build more phrases on to the categories. These phrases could be: • Noun phrases • Adverb phrases • Prepositional phrases • Adjective phrases
What about? • The dog ? • The park?
A simple noun phrase (NP) • Determiner (Det.) + Noun (N) = Noun Phrase (NP) the dog the park NP NP Det N Det. N
Noun phrase (NP) • A name is also a noun and attaches to a noun phrase Romeo NP N
What about ? in the park
Prepositional Phrase (PP) • Preposition + NP = Prepositional Phrase (PP) in + = the park in the park P PP NP P NP Det N Det N
What about ? quickly
Adverb Phrase (Adv.P) • When there is just one adverb, it attaches to an Adverb Phrase (Adv.P) quickly Adv.P Adv
What about hairy
Adjective Phrase (AP) • A single adjective attaches to an Adjective Phrase (AP) hairy AP A
More on adjectives • Adjectives are often found in sentences as modifiers of nouns: thehairydog modifier of noun • In this case they form part of a more complex noun phrase …
More complex noun phrases • … and they are analysed like this: the hairy dog NP AP Det N A
Now we go back to the sentence and start to decorate the tree ………
Inserting the phrases • The subject NP is easy to insert……………….……………… but the VP is more difficult the hairy dog walks quickly in the park S NP VP AP Det A N V Adv P Det N
First you attach the Verb the hairy dog walks quickly in the park S NP VP AP Det A N V Adv P Det N
Then you attach the AdvP the hairy dog walks quickly in the park S NP VP AP AdvP Det A N V Adv P Det N
Then you attach the PP the hairy dog walks quickly in the park S NP VP PP NP AP AdvP Det A N V Adv P Det N
What a complete tree looks like • a sentence divides into a noun phrase ……………….. and a verb phrase these attach to phrases or and categories categories attachto words the hairy dog walks quickly in the park S NP VP PP NP AP AdvP Det A N V Adv P Det N
How to analyse the syntactic structure of a simple sentence It’s a bit like decorating a Christmas tree: • Write S NP + VP at the top • Write the words of the sentence at the bottom • Write the categories above the words • Where necessary put the categories into phrase structures (NP, Adv,P, AP, PP) • Attach the phrase structures to the main NP and VP
Step 2 – write the words at the bottom the hairy dog walks quickly in the park S NP VP
Step 3 – write the categories of the words the hairy dog walks quickly in the park S NP VP Det A N V Adv P Det N
Step 4 – put the categories into phrase structures where necessary the hairy dog walks quickly in the park S NP VP PP NP AP AdvP Det A N V Adv P Det N
Step 5 – attach the phrase structures to the main NP and VP the hairy dog walks quickly in the park S NP VP PP NP AP AdvP Det A N V Adv P Det N
Juliet • Juliet N

Romeo • Romeo N
Romeo/Juliet loves Juliet/Romeo • Juliet loves Romeo Romeo Juliet S NP VP NP N V N

11. She solved the mystery • She solved the mystery S NP VP NP V PRO Det N
12. The witnesses helped her • The witnesses helped her S NP VP NP DET N V PRO
13. Alice followed the rabbit • Alice followed the rabbit S NP VP NP N N V Det.
