Creativity of Language
“Any speaker of a human language can
produce and understand an infinite
number of sentences.”

Syntax
“The part of the grammar that
represents a speaker’s knowledge of
sentences and their structures is called
syntax.”
Fromkin, Victoria, Robert Rodman & Nina Hyams. 2003. An Introduction to

Why Native Speaker
Grammaticality Judgments are
Basically the Same
Because native speakers of a language
share the same set of syntactic rules
their grammaticality judgments will be
the same.
How can we judge
what is grammatical?
1. Does NOT depend on whether you have
heard it before
2. Does NOT depend on whether it is
meaningful
3. Does NOT depend on whether you can
interpret it
4. Does NOT depend on whether it is true
5. It DOES depend on our “unconscious
knowledge of the syntactic rules of grammar”

Language. Boston, MA: Wadsworth, pp. 120-121.
