== Two approaches to grammar modeling ==

=== Constituency grammar [Martin, Jurafsky, 2000] ===

Phrase structure organizes words into nested constituents

=== Dependency grammar [Martin, Jurafsky, 2000] ===

Dependency structure shows which words depend on (modify or are arguments of) which other words.

TBD

=== Exercise 4.1 ===

Construct constituency and dependency trees for the sentences:

* "Susan wants to marry Lary."
* "They saw a man with the telescope."
* "Why do we say that the earth moves around the sun?"
