Rules of Syntax The rules of syntax combine words into phrases and phrases into sentences. Among other things, the rules determine the correct word order for a language. The rules of the syntax also specify the grammatical relations of a sentence, such as subject and direct object. 5. Your dog chased my cat. 6. My cat chased your dog.
Structural Ambiguity [old men] and [women] [old [men and women]]
Ambiguous Sentence (1) He went to the bank.
Ambiguous Sentence (1) He went to the bank. Lexical Ambiguity
Ambiguous Sentence (2) The girl saw the boy with a telescope.
Ambiguous Sentence (2) The girl saw the boy with a telescope. saw the boy with a telescope saw the boy with a telescope Syntactic Ambiguity
I shot an elephant in my pajamas. shot an elephant in my pajamas shot an elephant in my pajamas I shot an elephant, wearing my pajamas. I shot an elephant that was in my pajamas.
What Grammaticality is Not Based On Colorless green ideas sleep furiously. A verb crumpled the milk. *Furiously sleep ideas green colorless. *Milk the crumpled verb a. We showed that the structure of a sentence contributes to its meaning. However, grammaticality and meaningfulness are not the same thing. Grammaticality also does not depend on the truth of sentences.

Constituency Tests stand alone test replacement by a pronoun move as a unit test The child found a puppy. What did you find? a puppy Where did you find a puppy? I found him in the park. John found a puppy and Bill did too. It was a puppy that the child found. A puppy was found by the child.

Phrase Structure Trees represent three aspects of a speaker s syntactic knowledge 1. the linear order of the words in the sentence 2. the identification of the syntactic categories of words and groups of words 3. the hierarchical structure of the syntactic categories (e.g., an S is composed of an NP followed by a VP, a VP is composed of a V that may be followed by an NP, and so one)
Phrase Structure Rules 1. S NP VP 2. NP Det N 3. VP V NP
Phrase Structure Rules The woman laughed. 1. S NP VP 2. NP Det N 3. VP V NP 4. VP V
Phrase Structure Rules The puppy played in the garden 1. S NP VP 2. NP Det N 3. VP V NP 4. VP V 5. VP V PP 6. PP P NP
