 Semantic context  Semantic context comprises those contextual features that determine or partly determine the content of context-sensitive expressions. This is the case of pronouns, whose linguistic meanings do more or less strictly constrain but do not determine their designata. Their meanings direct us to the context (linguistic context, in cases of anaphoric co-designation; extra-linguistic context in cases of indexicals and deictic uses of demonstratives) to look for the designation of the pronoun. But there are more context-sensitive expressions than indexical, deictic and anaphoric pronouns. Sentence mood, for instance, is an indicator of illocutionary point, but it does not determine the precise illocutionary force of an utterance without the help of contextual factors. The contribution to utterance-content of some particles like ‘but’ (that, according to Grice, produce ‘conventional implicatures) are another case in point.
