An Interesting Feature of These Rules:As we saw last time, these rules allow sentences to containother sentences.

The Consequences of RecursionQuestion:So what? What’s so neat about ‘recursion’?
Answer, Part 1:Once recursion gets started, it never has to stop.
I Once the rules allow a sentence inside a sentence...(Dave thinks that he is cool)
I ...then they also allow a sentence in a sentence in a sentence...(Mary said that Dave thinks that he is cool)

Conjunction of Prepositional PhrasesOur Updated PS Rules:S → { NP , CP } VPNP → (D) (A*) N (CP) (PP*)NP → NP and NPVP → V (NP) { (NP) (CP) } (PP*)VP → VP and VPPP → P (NP)CP → C S
The Pattern:Wherever English allows one PP, it also allows two PPs joinedtogether by ‘and’.
Temporary Solution:Let’s introduce the following, additional rule for PPs:
PP → PP and PP(A PP can be formed from two other PPs joined by ‘and’).

Questioning by RepetitionCrucial Fact:In dialogs, we can only ‘quizzically repeat’ a constituent.
The Constituency Test:If we’re not sure if some bunch of words forms a constituent,we can use ‘quizzical repetition’ as a test:
I Imagine someone says the sentence, and then try to ‘quizzicallyrepeat’ those words.
I If it sounds natural, then those words form a constituent!I If it doesn’t, they they don’t form a constituent!
Illustration: “Dave walked into the house”
I Our rules predict that ‘walked’ and ‘into the house’ form aconstituent (VP).

Questioning by RepetitionCrucial Fact:In dialogs, we can only ‘quizzically repeat’ a constituent.
The Constituency Test:If we’re not sure if some bunch of words forms a constituent,we can use ‘quizzical repetition’ as a test:
I Imagine someone says the sentence, and then try to ‘quizzicallyrepeat’ those words.
I If it sounds natural, then those words form a constituent!I If it doesn’t, they they don’t form a constituent!

Applying Our Constituency Tests!Key Fact:The sequence ‘Aux VP’ does pass our constituency tests!
1. The Conjunction Test:The sequence ‘Aux VP’ can be followed by ‘and’ plus another‘Aux VP’ sequence:
I Dave has bought a car and will buy a house.
2. The Repetition Test:The sequence ‘Aux VP’ can be ‘quizzically repeated’
I Person 1: ‘Dave will buy a house.”I Person 2: ‘Will buy a house?!?”
Conclusion:The ‘Aux’ does form a constituent with the VP that follows it.
