Making it stick together…
Quite a Complexion

Why Syntax?
Universal Grammar
All languages have Words Rules
Merge Move
Syntactic Category: NP
_________ was given a flag.
The son of Isabel and Sam Isabel’s son The boy Joe
Key Vocabulary
Constituent Groups and subgroups of words that
“go together”
Syntactic category Constituents that can be substituted for
one another with loss of grammaticality NP, PP, Art, Conj, S, VP, Adj, Pro…
Syntactic Category: VP
Joe __________________.
Finish the sentence
Key Vocabulary Constituent structure tree
AKA: Phrase-structure tree
Diagram of a phrase or sentence that reduces repetition by the use of syntactic category labels in the branches of a tree
Constituency Tests
Substitution Pronoun Question Word
Relocation Conjunction …. but
Ambiguity≠ All for 1 & 1 for all
Phrase Structure Rules: English
NP N Joe NP Art + N the boy NP Art + Adj+ N the big boy NP Pro he
N NP Art (Adj)* + N
Pro{ }
Phrase Structure Rules: Cont’d
NP Art (Adj)* + N *the house red
Spanish: la casa roja *la roja casa
You tell me… a NP rule for Spanish
You tell me:
*John found. John found a ball. John found a ball in the grass. *John found in the grass.
A VP phrase-structure rule would be: VP Vt + NP (PP)*
Key Vocabulary Phrase Structure Rules
Specify grammatical ways of putting sentences together
Lexical insertion rules Match syntactic categories with words or morphemes
at the bottom of a tree Subcategorization
Restricts how lexical items can occur
Examples: Transitive Verb: VP Vt + NP (adj)
Find, love, destroy Intransitive Verb: VP Vi (adv)*
Die, sleep
Ambiguity The son of Isabel and Sam
You tell me… Where is the break for each meaning?

Key Vocabulary
Transformational rule an operation that moves, deletes, or
inserts a category a rule that applies to a syntactic tree
to yield a new syntactic tree.
Additional Notes (value of trees)
Structure Dependent Rules Surface words ≠ important Transformational rules constituents
Head NP agrees with Main VP Regardless of intervening structures Regardless of transformations
Syntax allows a NS to: produce and understand an infinite set of utterances distinguish between grammatical and ungrammatical
strings interpret certain strings as well-formed grammatically but
ill-formed semantically interpret certain strings as well-formed semantically but
ill-formed grammatically understand the full meaning of a sentence from a string
of words, which may not contain all the words necessary for an accurate interpretation
perceive when two or more strings are synonymous (paraphrase)
perceive structural ambiguity in a grammatical string account for grammatical and logical relations within a
sentence
Q: What’s the best way to help a NNS internalize the same?
Additional Structures
Coordination Pulls two parts together
Relatives Tells more about an NP
Passives Changes the focus De-emphasizes or obscures the
‘actor’
