Identifying word classes
Overview
Identifying word classes
 Syntax of the major word classes
 Grammatical categories

Syntactic criteria

Distribution
Only the same members of one specific word
class can be filled in the same slot in a sentence.
 Each word class has its own specific set of
modifying words

Morphological criteria

Form

The specific set of affixes in the form of words
shows that the words belong to the same word
class.
Case Study: Identifying the word class
of ‘barista’

Data
A barista is a coffee master of making coffee.
 Baristas are in charge of training new

Questions:
How do we identify the word class of 信 in ‘他
