Accommodation and Presupposition<br />

additional effort and will generally be considered by the <strong>in</strong>terpreter to be a less<br />

natural read<strong>in</strong>g.<br />

When we are presented with examples where the presupposed <strong>in</strong>formation is<br />

already embedded under some type of logical operator, it is more often than not<br />

without a context. But how can we use decontextualized examples to illustrate and<br />

make conclusions about preferences for presupposition projection when everyone<br />

agrees that resolv<strong>in</strong>g a presupposition to the right level of accommodation is a<br />

context-dependent process. There may be a preference to use presuppositions with<br />

higher levels of accommodation, but I am not sure if we could ever prove or<br />

disprove it us<strong>in</strong>g this particular method.<br />

Other work has also po<strong>in</strong>ted out that decontextualized examples will often<br />

give mislead<strong>in</strong>g <strong>in</strong>formation about preferences. For example, Del<strong>in</strong> (1995) has<br />

shown that the use of decontextualized examples <strong>in</strong> the literature on it-cleft<br />

presuppositions has led to it-cleft presuppositions <strong>in</strong>correctly be<strong>in</strong>g confused with<br />

shared-knowledge. She po<strong>in</strong>ts out that this is because the <strong>in</strong>tonation associated<br />

with a decontextualized, unmarked it-cleft <strong>in</strong> written form phonetically focuses the<br />

clefted constituent and the cleft complement is not focused at all. This <strong>in</strong>tonation<br />

strongly suggests that the presupposed <strong>in</strong>formation is shared <strong>in</strong>formation. But<br />

naturally produced clefts regularly appear with different <strong>in</strong>tonation patterns and<br />

these lead to different <strong>in</strong>terpretations of the presupposition. Add<strong>in</strong>g explicit<br />

<strong>in</strong>formation about prosodic prom<strong>in</strong>ence is a way to simulate context, and can<br />

thereby force a read<strong>in</strong>g with local or <strong>in</strong>termediate accommodation. This is<br />

illustrated <strong>in</strong> the examples below. The a-sentences are presented without marked<br />

<strong>in</strong>tonation, and the b-sentences have been marked to encourage a particular<br />

prosodic realization. The a-sentences strongly suggest a read<strong>in</strong>g with global<br />

accommodation, whereas the b-sentences strongly suggest a read<strong>in</strong>g with local<br />

accommodation.<br />

(46) a. John might know that Mike has been steal<strong>in</strong>g funds.<br />

b. John MIGHT KNOW that Mike HAS been steal<strong>in</strong>g funds.<br />

b-sentence suggests: we are not sure if Mike has been steal<strong>in</strong>g funds.<br />

(47) a. John might not know that a decision was made.<br />

b. John MIGHT NOT KNOW that a decision WAS made.<br />

b-sentence suggests: we are unsure if a decision was made<br />

Analogous to the it-clefts studied by Del<strong>in</strong> (1995), default <strong>in</strong>tonation conspires to<br />

encourage the impression that the presupposed <strong>in</strong>formation is shared <strong>in</strong>formation,<br />

– “normal” or “default” <strong>in</strong>tonation of decontextualized examples lead us to believe<br />

that this is the default usage. I would argue further that especially for factives, the<br />
