Workshop 5Formal Approaches to the
Relation of Tense, Aspect and Modality
CoordinatorsYukinori Takubo Stefan KaufmannKyoto University Northwestern University
Basic ideas behind the theme of the workshop
A: Forms that express tense, aspect and modality may be related, or may be the same in some languages.
B: Devise some formal mechanisms that explain A, if A is the case
2
A case study:
• tokoro-da in Japanese
• Aspectual forms+tokoro-da:
Immediacy
• Conditional consequence+tokoro-da: Counterfactuality
3
Some basic facts• Non-past form: RU /ru/~/u/
• Past form:TA /ta/~/da/
• Progressive form: TEI
4
Nonstative verb+RU
Event e succeeding the reference time r (or ut): future, either remote or immediate
John-wa akai zyaketto-o ki-ru TOP red jacket-ACC wear-RU
John will wear a jacket {now, for his 60th birthday in two years}
5
Nonstative+TA
Event e immediately or remotely preceding r (or ut)
John- wa akai zyaketto-o ki-ta TOP red jacket-ACC wear-TA
John wore a jacket {just now, for his 60 the birthday in two years ago}
6
Stative+ru/ta• When attached to statives /-ru/ means that a stative eventuality e holds at r preceding
ut.
Watasi-ni wa eigo-ga hanase-ru . I-Dat TOP English-NOM can_speak-RU 'I can speak English (now).'
/-ta/ means that a stative eventuality e holds at r succeeding ut.
Watasi-ni wa eigo-ga hanase-ta . I-Dat TOP English-NOM can_speak-TA 'I was able to speak English (then).'

tei form
John- wa akai zyaketto-o ki-tei {ru,ta} TOP red jacket-ACC wear-TEI {RU,TA}
John is putting on a red jacket. Progressive
John has a red jacket on. Resultative state
(Li.) John has worn a red jacket ten years ago (for his 60th birthday). Perfect or past experience

ru-tokoro-da
• Only immediate future reading is possible for V-ru tokoro-da
Watasi-wa ima-kara akai jacket-o ki-ru tokoro-daI-TOP now from red jacket-ACC wear-RU TOKORO-COP
I am going to put on a red jacket from now.
* Watasi-wa 2 nen go ni akai jacket-o ki-ru tokoro-daI-TOP two years from now red jacket-ACC wear-RU TOKORO-COP
I am going to put on a red jacket 2 years from now
10
Ta-tokoroda
Only immediate past reading for V-ta+tokoro-da
Watasi-wa ima akai jacket-o ki-ta tokoro-daI-TOP now red jacket-ACC wear-TA TOKORO-COP
I have just put on a red jacket.
* Watasi-wa 2 nenmae ni akai jacket-o ki-ta tokoro-daI-TOP two years from now red jacket-ACC wear-RU TOKORO-COP
I put on a red jacket 2 years ago
11
te i-ru+ tokorodaOnly progressive reading is possible for tei{ru/ta} tokoroda
a. John- wa akai zyaketto-o ki-tei {ru,ta} tokoro-da TOP red jacket-ACC wear-TEI {RU,TA} tokoro-COP
John is putting on a red jacket. Progressive
b. *John- wa sakki kara akai zyaketto-o ki-tei {ru,ta} tokoro-da
TOP a moment since red jacket-ACC wear-TEI {RU,TA} tokoro-COP
John has a red jacket on since moment ago. Resultative state
c.*John- wa 2 nenmae akai zyaketto-o ki-tei {ru,ta} tokoro-da TOP 2 yeas ago red jacket-ACC wear-TEI {RU,TA} tokoro-COP
(Li.) John has worn a red jacket ten years ago (for his 60th birthday). Perfect or past experience
Counterfactual interpretation of c is possible.
12
Stative verbs+tokoro-da:tokoro-da cannot be attached to stative verbs
*Watasi-ni wa eigo-ga dekiru tokoro-da. I-Dat TOP English-NOM can-TOKORO-COP 'I can read English.'
• Stative+tokoro-da must be interpreted as counterfactual, rather than aspectual.
Watasi-ga America-de umareteitara, eigo-ga hanaseru tokoroda. I-NOM America-LOC was-born-if English-NOM can-speak TOKORO-COP If I were born in America, I would be able speak English now.

Relational noun for time:go-home>have-dinner>brush-teeth>go-to-bed. (25) Neru mae-ni ha-o migaku.
go-to-sleep before teeth-ACC brush (I) brush teeth before going to bed.
neru(e)<go-to-bed(e)
ha-o migai-ta ato-de neru teeth acc brush after-LOC sleep (I) go to bed after brushing my teeth. mae-ni (x,y) : x is before yneru mae-ni ha-o migaku ha-o migaku‘(e)<neru‘(e)
ato-de (x,y): x is afer yha-o migai-ta ato-de neru ha o migaku’(e)<neru’(e)
Neru' is the point of reference for the temporal relation before.
18
Tokoro as a marker for the point of
reference.
Tokoro is can be considered as a special kind of relational noun representing a reference point:
R(x,y) [(x is at y) & y is the reference point]
Spatial relation:no higasi (x,y) : x is on/ to the east of yno mae (x, y) : x is in front of yno tokoro (x,y): x is (not in front of or east of but) at y Temporal relation mae-ni (x,y): x takes place before y ato-de (x.y): x takes place after y tokoro-de (x.y): x takes place (not before or after but) at y
19
ru-form: <----------r-------- [ e ] in contact with (r,e) or preceding (r, e)
ta-form: [ e ]-----r-------------------- in contact with (r,e) or succeeding (r,e)
tei-form: [ -- e--r---] --------r-- included (r, e) or succeeding (r, e)
e is the reference point in each tense/ aspect expression
20
tokoro picks out e as the point of reference: r at e.
ru-tokoro-da form: <----------r-------- [s e f] in contact with or preceding (r, e) and r at e : r in contact
with the start time of eta-tokoro-da form: [s e f]-----r-------------------- in contact with or succeeding (r,e) and r at e: r in contact
with the finishing time of e
tei-(ru/ta)-tokoro-da form: [s -- e--r--- f]-- -r---------
{included (r, e) or succeeding (r, e) } and r at e: included (r,e)

• tokoro-da can be either temporal or modal.
• Nonstative+tokoro-da can either be temporal or modal.
• Stative+tokoro-da can only be modal.
Why?
22
• Nonstative eventuality: r: R(r,e)
R: precedence, inclusion, succession
• Stative eventuality: true at r : e⊃r
• tokoro-da restricts R to inclusion, which, in the case of statives is redundant if interpreted temporally, hence the obligatory modal interpretation
23
But why counterfactual?
24
Assumption
A: Lexical properties of tokoro as a point of reference forces sentences with tokoro-da to be interpreted as an eyewitness report, thereby committing the speaker to its truth.
We will show the assumption A is enough to derive the counterfactual status of stative+tokoro-da conditionals.
25
a. if p then q tokoro-da
By the lexical properties of tokoro-da, the
speaker knows that q is true in a. So b holds.
b. q is true∧ (p→q)
Given b, saying just q is more informative than saying a, unless by a you want to say q if p (or q iff p).
• (the speaker knows q is true) and (q only if p). The three possible cases for the status of p.
a)the speaker knows that p is true.
b)the speaker knows that p is false.
c)the speaker does not know whether p is true or false.
Since q is true, q only if p should be false if (b) is true. Since q only if p, if the speaker knows q is true, then he should know that p is true, because p is the necessary condition for q to hold. So c cannot be the case.
• The speaker knows that p is true.
a. Suppose the speaker assumes that the hearer believes not p is true. ¬ p∧q
In this context conditional forms are inappropriate to correct the hearer’s assumption in J. Concessive forms must be used.
• b. Suppose the speaker knows p is true and assumes that the hearer does not know whether p is true.
Conditional forms are not appropriate. Reason forms must be used.
• Conditional forms cannot be used if the speaker knows that q is true!
• Suppose the speaker knows that q is false, that is, ¬ q is true.
the speaker knows that p is true ->the conditional becomes false, violating Grice’s maxim of quality.
the speaker know that p is false->the conditional sentence is okay!
conditional tokoro-da location on the vertical axis
q --------B--- closest counterfactual situation
p ( p,q)
E ------------A---- reality ( ¬ p, ¬ q)
¬ p ¬ q
Summary
i) tokoro-da can be either temporal or modal (or spatial).
ii) Nonstatives-tokoro-da can either be temporal or modal.
iii) Statives-tokoro-da can only be modal and counterfactual.
• iv) (iii) is to be attributed to the the lexical meaning of tokoro as a reference point marker :
• tokoro places r at e• q tokoro-da is part of the reality where the
speaker’s point of view is.
This is a case where tense, aspect and modality meet.

Conclusion
• Let us talk about things like this in this workshop and try to find how they can be formalized!
