1 - Properties of Quantifiers
Conservativity
The conservativity of a natural language quantifier Q can be defined as follows: given two sets A and B, ∈ [Q]M iff ∈ [Q]M.
As an example, consider the following sentence:
(1) Every child plays.
This sentence is true in M iff <[child]M, [plays]M> ∈ [every]M. If every is conservative, we also expect that <[child]M, [child]M ∩ [plays]M> ∈ [every]M. This could be paraphrased as Every child is a child that plays.
a) Show that every is conservative by constructing a model M in which <[child]M, [plays]M> ∈ [every]M (i.e., in which (1) is true). To do so, provide the extensions of [child]M and [plays]M in list notation, and briefly explain why <[child]M, [plays]M> ∈ [every]M holds. (You will need to go back to the extension of the quantifier). Then, explain why it also holds that <[child]M, [child]M ∩ [plays]M> ∈ [every]M.
b) Show that some is conservative. Assume that the following sentence is true in M:
(2) Some books are interesting.
c) Show that no is conservative. Assume that the following sentence is true in M:
(3) No book is boring.
d) Now consider the following hypothetical quantifier:
[wug]M = {
Discuss whether wug is conservative, taking as a starting point the following sentence:
(4) Wug book is interesting.
Hint: consider both conditions that must be met for wug to be conservative.
I.e., for any two sets X and Y, it must hold that
e) Consider another hypothetical quantifier (notice a crucial difference with respect to the denotation of every):
[wis⟧M = {
Discuss whether wis is conservative, following the same hint provided for wug and taking as a starting point the following sentence:
(5) Wis student left.
Monotonicity
Determine the monotonicity patterns of the following quantifiers. To do so, for each quantifier Q construct a model M such that given an arbitrary NP and an arbitrary VP, <[NP ⟧M, [VP ⟧M> is a member of [Q⟧M. This implies that a certain relation must hold between [NP ⟧M and [VP ⟧M. To work on monotonicity, you may want to refer to a subset and a superset of [NP ⟧M and a subset and a superset of [VP ⟧M.
Then, determine whether the quantifier is ↑MON, ↓MON, MON↑, or MON↓ . Remember that it is generally easier to prove that a certain property does not hold. For the purposes of this assignment, it will be sufficient to show that a given relation does hold in at least one situation to show that the relevant quantifier is monotonic in the relevant direction (e.g. ↑MON).
As an example:
(i) Every student left.
NP |
NP subset |
NP superset |
[student⟧M = {a} |
[undergraduate student⟧M = ∅ |
[person ⟧M = {a, b, c} |
VP |
VP subset |
VP superset |
[left⟧M = {a, b} |
[left early⟧M = ∅ |
[moved⟧M = {a, b, c} |
↑MON: every is not ↑MON. Every student left does not entail every person left. There may be a situation in which some people who are not students did not leave.
↓MON: every is ↓MON. Every student left entails every undergraduate student left.
MON↑: every is MON↑ . Every student left entails every student moved.
MON↓: every is not MON↓ . Every student left does not entail every student left early. There may be a situation in which all students left late.
f) exactly two
There is no need to construct another model; simply refer to your intuitions. You can use the sentence Exactly two students left as a starting point.
g) between five and ten
There is no need to construct another model; simply refer to your intuitions. You can use the sentence Between five and ten students left as a starting point.
h) wug
Remember: [wug ⟧M = {
Conjunction and disjunction of QPs
Consider the following sentences:
(6) Every woman but no man agreed with the president.
(7) *A man but every woman agreed with the president.
i) Based on the above data, what generalisation can you make about two QPs coordinated by the conjunction but? Provide a short explanation and cite any relevant source you may have found.
(Hint: consider the rightward monotonicity of the quantifiers.)
2 - Negative Polarity Items (NPIs)
Licensing of any
The Fauconnier-Ladusaw Hypothesis states that NPIs are licensed in downward-entailing (DE) environments.
a) Consider the following sentence:
(8) Exactly two people saw anything. Is this unexpected? Explain briefly why.
Licensing environment and their negative strength
We have seen that different NPIs require licensers with different negative strengths (non-veridical, DE, anti-additive, antimorphic).
b) Consider the distribution of either in English:
(9) a. Mary didn’t come either. b. Mary never came either. c. *Did Mary come either?
For comparison with any:
(10) a. Mary didn’t eat any chocolate. b. Mary never ate any chocolate. c. Did Mary eat any chocolate?
What generalisation can you make about the type of licenser that either requires, based on the data?
c) Consider the following contrast between English and Japanese:
(11) a. I didn’t see any students. (English) b. If you see any student, inform. me.
(12) a. Watasi-wa gakusei-o hito-ri-mo mi-nakat-ta. (Japanese) I-top student-acc one-cl-MO see-neg-past
‘I didn’t see any students. ’
b. *Gakusei-o hito-ri-mo mita-ra siras-ero.
student-acc one-cl-MO see-if inform.IMP
Intended: ‘If you see any student, inform. me. ’
How can you explain the contrast between any in English and hito-ri-mo in Japanese?
3 - Quantifier Scope
The following sentence is ambiguous:
(13) Every student read a French novel.
a) Represent the two readings in predicate logic, using the following predicate letters: S = student R = read (2-place) N = novel F = French
b) Does the surface scope reading entail the inverse scope reading? If it does not, briefly present a situation in which the surface reading is true but the inverse reading is false.
c) Does the inverse scope reading entail the surface scope reading? If it does not, briefly present a situation in which the inverse reading is true but the surface reading is false.
Now consider the following ambiguous sentence:
(14) Every politician is not corrupt.
Here the scope relations are between the quantifier and negation.
d) Represent the two readings in predicate logic; assume that P = politician and C = corrupt.
e) Does the surface scope reading entail the inverse scope reading? If it does not, briefly present a situation in which the surface reading is true but the inverse reading is false.
f) Does the inverse scope reading entail the surface scope reading? If it does not, briefly present a situation in which the inverse reading is true but the surface reading is false.
4 - Tense and Aspect
a) Based on the following data:
(15) a. ?Mary builds a house.
b. Mary is building a house.
(16) a. Mary knows French.
b. *Mary is knowing French.
What generalisation can you make about a verb’s ability to appear in the present tense ((a) sentences) or in the progressive ((b) sentences) depending on that verb’s Aktionsart (aspectual class)?
b) In the Reichenbach-Klein theory of tense-aspect, there are three main coordinates: Utterance Time (UT), Reference Time (RT), and Event Time (ET).
In the present tense, we can assume that UT = RT and RT = ET. In the simple past, on the other hand, RT < UT and RT = ET:
(17) [Assume now = 6pm]
Mary ate at 4pm. UT: now; RT: 4pm; ET: 4pm
Now consider the following tenses:
(18) At 4pm, Mary had eaten.
(19) At 4pm, Mary will have eaten.
What precedence (<) relations between ET and RT, and between RT and UT, can be established in
(18) and (19), respectively?
