Syntax 1 Wiki: Week 5

Tracking the stucture-building process in detail

This week we are going study every detail of the licensing of phrases. For this purpose, we are going to study the interaction of the following concepts:

1. Word definitions
2. Phrase definitions (again)
3. Unification (= the merging of feature structures)

Unification

We begin with the concept of unification. It simply means that you combine the information that you have about an object from two or more sources. Or, to put it differently, you combine two descriptions of the same object. Here is an example.

Imagine that Jill and Jack are at the Frankfurt Christmas market together. At some point, they see a pickpocket stealing somebody's purse. By the time they have alerted the police, the pickpocket has disappeared. The police officer asks them for a description of the pickpocket and gets the following answers:

Jill: the pickpocket

• is a man
• has blond hair
• was wearing a jacket
  • the jacket was black

Jack: the pickpocket

• is a man
• was wearing a jeans
• was wearing a jacket
  • the jacket had a zipper rather than buttons
