Due 4/1/05

Getting Started

Feature Structure Re-entrancies in Agreement

Phrase Structure Rules

Your answers to the questions below should be included in your write-up.


This grammar does not yet have any account of modification. In this part, you'll add PP modifiers and the types and rules that support them.

The Head Feature Principle

Looking at the various rules, you'll notice that the HEAD value of the whole phrase is always identified with the HEAD value of one of the ARGS, sometimes the first and sometimes the second. In this part, you'll modify the grammar to reflect this distinction between head-initial and head-final phrases.

Eliminating Redundancy in the Lexicon

The grammar so far lacks any lexical type hierarchy. We'll fix that now.
