"How Language Works" - see old ch4 notes too
words/morphemes, concepts, syntax
two tricks of L
independence from cognition
any model of L must include phrases (trees, hierarchical structure,)
Human languages do not show their tree structure directly though it is coded into word order, inflection, syntactic rules and prosody.

language ambiguity
Chomsky's goal of describing "univeral grammar"  (UG)
combinatorial semantics assumption
a sentence is complex phrase composed of phrases
phrases refer to the interaction of "role players"
languages may differ in:
Verbs as "despots"
Cases indicate roles NPs play in the sentences. 
Auxiliaries indicate truth of propositions implicit in the S
complex sentences
empty categories and traces
pronouns and coreference
why grammar?
