THEORETICAL
BACKGROUND
3
What is focus?
(1)
Q: Who likes Sue?
A: [Mary]F likes Sue
(alternatives: [Jane]F likes Sue, [Peter]F likes Sue, etc.)
A: * Mary likes [Sue]F
• Focus does not have to be “new”, but must be unpredictable
(not yet in the common ground). (Beaver & Velleman 2011)
(2)
Gary, Larry, Harry, Barry and Mary all showed up at the
party. And you won't believe who got the drunkest. It was_____ !
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Universal category of information structure (Krifka 2008)
• Focus evokes a set of alternative propositions which the
speaker takes to be salient (Rooth 1992)
4
Two types of focus
• Identificational focus
Associated with a semantically stronger interpretation:
Exhaustive
Contrastive
Corrective
Verum
(4)
S1: Last Halloween, John went as Batman.
S2: No, John went as [Spiderman]F.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Informational focus
(3)
Q: Who is chewing tobacco?
A: [John]F is chewing tobacco.
5
• Different across languages (Büring 2008)
(5)
Q: Who is chewing tobacco?
A: JOHN is chewing tobacco
English
A: C’est Jean qui mâche du tabac
French
A: Está masticando tabaco Juan
Spanish
• Identificational focus must be realized in a special
position, via more marked strategy (Kiss 1998)
(6)
A: It’s John who is chewing tobacco it-cleft
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
How is focus realized?
6
The English it-cleft
It’s John who is chewing tobacco.
• Associated with an exhaustive inference (a)
• and/or contrast (b)
(a) Nobody other than John is chewing tobacco.
(b) John as opposed to, for example Mary, is chewing
tobacco.

Contrast
• Exclusion of alternatives (Kiss 1998)
• Presence of an explicit antecedent focal alternative
(Rooth 1992; Schwarschild 1999)
• Account for why clefts are good as corrections but sound
odd as direct answers to explicit wh-questions.
• … but some facts remain unexplained.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Previously understood on the basis of semantic terms:
8
Motivation for the current study
• In contexts in which an antecedent is available,
speakers may nevertheless choose not to use an itcleft.
(8) S1:Darren sounded really excited about his
vacation. I think he’s going to Canada.
S2a: Actually, he’s going to Mexico.
S2b: ? Actually, it’s Mexico that he’s going to.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• In contexts where the speaker provides a complete,
exhaustive answer, the it-cleft is not always
produced.
9
• Exhaustivity and presence of a focal antecedent may be
necessary conditions, but we think they are not sufficient
to explain the natural use of the cleft in English …
What more is needed ?
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
So …
10
Specific research questions
• How can the notion of contrast be refined to reflect
these factors?
• What might this mean for the bigger cross-linguistic
picture?
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Under which conditions are it-clefts actually produced in
English? What factors are relevant for their felicity?
11
Broaden the notion of contrast to include two features:
• LINGUISTIC: Rooth-style contrast with a prejacent
proposition.
 Makes clefts more felicitous.
 Directly promotes cleft production.
• METALINGUISTIC: Conflict with hearer’s expectations.
 Takes the discourse in an unexpected direction.
 Makes canonical sentences less felicitous, which
indirectly promotes cleft production.

PRODUCTION STUDY:
14
Goal of the study
• An observation: natural English it-clefts often seem to
be counter-presuppositional … not informational.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• A practical goal: how to elicit felicitous it-clefts?
15
Counter-presuppositional context:
• Correction: Ken.
• You say: __________________________________

• Your friend says: We were planning Amy's surprise party
for weeks. I can't believe someone ruined the surprise.
Do you have any idea why Alice told her about it?
16
Informational context:
• Answer: Ken.
• You say: ___________________________

17
 Counter-presuppositional contexts will elicit clefts
where informational contexts did not.

Methodology
•
•
•
•
15 native English speakers (UT undergraduates).
5 lexicalizations created per context.
2 versions of the written questionnaire.
Each participant saw a total of 10 experimental stimuli +
5 fillers.
• Collected 150 sentences.

2 x 2 design:
• context (informational/ counter-presuppositional)
• grammatical function of element in the answer
(subject/ object).

Informational
Counter- presuppositional
• Difference in distribution of sentence form across both
contexts is highly significant. (χ2 (1) = 36.24, p<0.01)
• Difference in distribution of sentence form in
informational context is highly significant. (z = 7.27,
p<0.01)
• Difference in distribution of sentence form in counterpresuppositional context is not highly significant. (z = 0.57, p=0.5)
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• The odds of using a cleft is 13.1 times higher given the
counter-presuppositional context than the informational
context.
21
Interim discussion
• While clefts are clearly contrastive, clefting is not the
only strategy available to speakers. Canonicals (with
prosodic prominence) are also produced.
 So, what makes a cleft a better alternative?
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• It-clefts are actually produced, mostly to offer a
correction to a presupposition. They do make really bad
direct answers.
22
DEGREE OF BELIEF OR
DEGREE OF AT-ISSUENESS?
Experiment 2
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
RATING STUDY:
23
The intuition behind this study…
• Question: what difference actually matters between the
informational & counter-presuppositional contexts?
• Intuition: cleft is doing more than just linguistic
contrast...
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• The production study can only tell us so much about the
cleft’s use.
24
 Two types of expectations seem important:
• Expectations about the world (Strength of belief)
• Expectations about the discourse (At-issueness)
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• The cleft seems increasingly better when the speaker’s
expectations are expressed more strongly, and the conflict
with hearer’s expectations intensifies.
(related to Zimmerman 2008, 2011)
25
Strength of belief
• Gradient notion:
“no overt belief”
“weak belief”
“strong belief”
• More strongly expressed beliefs lead to stronger conflict
between interlocutors.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Expectations involving speaker’s beliefs about the world
(common ground)
… expressed as assertions or presuppositions.
26
At-issueness
• At-issue: asserted content. “The main point of the
utterance”
• Non-at-issue: presupposed content. “propositions
which the sentences are not primarily about”
(Simons et al. 2010, Tonhauser 2012, Tonhauser et al.
2013)
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Expectations the speaker has about the direction in which
discourse is progressing…
… expressed by marking (part of) the proposition as:
27
Hypothesis
• clefts will become increasingly felicitous as
strength of belief increases, and vice-versa for
canonicals.
• clefts will become increasingly felicitous when
the proposition corrected is not-at-issue, and
vice-versa for canonicals.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
Both factors Strength of belief and At-issueness play
a role in the felicity of the it-cleft:
28
Stimuli
“This bean dip is fantastic. I really want the recipe...
• …Who made it ?”
Informational
• …I guess maybe Shannon made it.”
At-issue weak belief
• …Shannon made it.”
At-issue strong belief
• …I can’t believe Shannon made it.”
Counter-presuppositional
Responses to rate:
• Actually, Tim made it.
• Actually, it was Tim who made it.

• Felicity judgment task on 1-5 point likert scale:
1- not natural at all, I would never say this.
3- sounds natural, I would sometimes say this.
5- extremely natural, exactly how I would say this.
• 12 native English speakers (undergraduates at St Edwards
University).
• 5 lexicalizations created per context.

DISCUSSION
35
Canonicals
• Strength of belief is not significant, but at-issueness plays a
role.
• Our interpretation:
The use-conditions of the canonical must make reference to
the distinction at-issue/ non-at-issue.
Canonical sentences are preferred when used to address or
contradict at-issue (asserted) content.
Canonical sentences signal “things are proceeding as normal”
and are infelicitous in contexts where the component
contradicted is non-at-issue.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Canonicals are significantly worse in the counterpresuppositional context than in the other three.
36
It-clefts
• Strength of belief has some effect, but it only slightly
significant.
• Our interpretation:
All it takes for the clefts to be felicitous is linguistic
contrast …
but for clefts to be preferred, the canonical must not be
available, and that due to metalinguistic contrast: conflict
about the direction of the discourse.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• It-clefts are significantly worse in the informational
context than in the other three.
37
• Clefts and canonicals are in competition.
• Clefts are felicitous when the canonical is a “bad” option.
• Specifically, clefts are better than canonicals in the
counter-presuppositional context due to a combination of
two effects:
• Clefts improve because there’s an antecedent.
• Canonicals degrade because the antecedent is not-atissue.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
Competition is key!
38
Summing up
• The notion of contrast must include a metalinguistic
component: conflict with hearer’s expectations, specifically
about the advancement discourse.
• So far, the only statistically significant feature is at-issueness:
canonicals are worse when addressing non-at-issue content.
• In-line with results on Chinese (Greif 2012) where increased
phonetic marking and clefts are produced with corrections of
presupposed information.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• It-clefts are used in English when the corresponding canonical
is less felicitous or unavailable.

CROSS-LINGUISTIC
IMPLICATIONS
40
What’s next: cross-linguistically
• … So why don’t all languages use clefts in the same
contexts?
 A speculative hypothesis: the felicity conditions for
canonical sentences vary.
• A canonical sentence signals “things are proceeding as
normal” – but what’s “normal” could vary.
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
• Felicity contexts for clefts (and other strong focus
constructions) are supposed to be the same
crosslinguistically…
41
What’s normal?
FRENCH: “Don’t use canonicals for subject focus.”
(normally, subjects are old information/ topics)
K’ICHEE’: “Don’t use canonicals for transitive subject focus.”
(normally, transitive subjects are old information)
HUNGARIAN: “Don’t use canonicals for partial answers.”
(normally, complete answers are preferred)
Destruel, Semantics Colloquium
Frankfurt, 01/21/14
ENGLISH: “Don’t use canonicals to address not-at-issue content.”
(normally, we discuss what’s at issue)
42
• A more thorough ratings experiment – having two
additional contexts:
 Informational
 At-issue weak belief
 At-issue strong belief
 Not at-issue weak belief
 Not at-issue strong belief
 Counter-presuppositional
• A production experiment covering all contexts.
• Run the experiment in the oral modality.
• Supplement with corpus data.
