 There are many possible responses to this challenge. One is to deny the relevant intuition. Perhaps the leaf really is green if it is painted green and (6) is uttered truly in both situations. Nonetheless, we might be sometimes reluctant to make such a true utterance for fear of being misleading. We might be taken to falsely suggest that the leaf is green under the paint or that it is not painted at all (cf. Sainsbury 2001 and Berg 2002). The second option is to point out that the fact that a sentence can say one thing on one occasion and something else on another is not in conflict with its meaning remaining the same. Do we have then a challenge to compositionality of reference, or perhaps to compositionality of content? Not clear, for the reference or content of ‘green’ may also change between the two situations. This could happen, for example, if the lexical representation of this word contains an indexical  element.[21]  If this seems ad hoc, we can say instead that although there is no context-dependent expression in (6) it can still be used to make both true and false assertions. Perhaps the compositionally determined occasion meanings are impoverished (perhaps not even propositional), which is why they tend to be different from what speakers assert (cf. Bach 1994 and Soames 2005).
