Syntactic Rules
Syntactic rules in grammar account for:
• The grammaticality of sentences
• Word order
• Hierarchical organization of sentences
• Grammatical relations such as subject and object
• Whether different structures have differing meanings or
the same meanings.
• The creative aspect of language

Syntactic Rules
• Syntactic rules determine the order of words in a
sentence and how the words are grouped.
- ‘The child found the puppy’ may be grouped into
(The child) (found the puppy)
(the child) (found) (the puppy)
• The natural groupings of a sentence are called
constituents
• The constituent structure may be represented as a tree
structure
• Multiple tree structure can account for structural
ambiguity
- synthetic buffalo hides = (synthetic) (buffalo hides)
(synthetic buffalo) (hides)

- Adverb (Adv)
Prepositional Phrase (PP)

Phrase Structure Tree
• A tree diagram with syntactic category information is
called a phrase structure tree or constituent structure
tree.
