3. Before you get confused…
Grammar
mental representation of a speaker’s
linguistical competence
what a speaker knows about the
language, including its phonology,
morphology, syntax, semantics and
lexicon
4. Before you get confused…
Syntax
the rules of sentence formation
the component of the mental
grammar that represents speakers’
knowledge of the structure of
phrases and sentence
5. Syntax
σύν syn, "together", and τάξις táxis, "an ordering“
arrangement
refer directly to the rules and principles that govern
the sentence structure of any individual language
structure (word order)
23. What Grammaticality is Not Based On
Not based on what is taught in school but on the
rules constructed unconsciously as children
Children acquire most of the syntactic rules of their
language even before learning to read.
Does not depend on having heard the sentence
before.
24. What Grammaticality is Not Based On
Not based on what is taught in school but on the
rules constructed unconsciously as children
Children acquire most of the syntactic rules of their
language even before learning to read.
Does not depend on having heard the sentence
before.
Example:
Enormous crickets in pink
socks danced at the prom.
25. What Grammaticality is Not Based On
Does not depend on the truth of the sentence
If it did, lying would be impossible.
Example:
26. What Grammaticality is Not Based On
Does not depend on the truth of the sentence
If it did, lying would be impossible.
Example:
I look like Piolo Pascual.
27. Syntactic Rules Accounts for:
Grammaticality of the sentence
Word order
Structural ambiguity
Grammatical relations
Whether different structures have different meanings
The creative aspect of language
28. What else do you know about syntax?
Ambiguity (Double Meaning)
Ex. synthetic buffalo hides
synthetic (buffalo hides)
(synthetic buffalo) hides
Grammatical Relations and how they are understood
Ex. Mary hired Bill.
Bill hired Mary.
Bill was hired by Mary.

44. The Infinitude of Language
There is no longest sentence in any language
Speakers can lengthen any sentence by various means
Adding adjectives, clauses, etc.
45. The Infinitude of Language
Example: House that Jack built (nursery rhyme)
This is the farmer sowing the corn,
that kept the clock that crowed in the morn,
that waked the priest all shaven and shorn,
that married the man all tattered and torn,
that kissed the maiden all forlorn,
that milked the cow with the crumpled horn,
that tossed the dog, that worried the cat,
that killed the rat, that ate the malt,
that lay in the house that Jack built.
