 We have distinguished several interpretations for the seemingly simple claim that a certain language is compositional and we picked a fairly natural one. Thus, we proposed to read  (C)  as being about meaning (as opposed to reference or some other value one might assign to expressions), that it postulates functional determination of meaning within a particular language (as opposed to across a class of languages), and that the determinants of the meaning of a complex expression are its entire structure (as opposed to just its immediate structure) and the meanings of its constituents individually (as opposed to collectively). We saw that  (C)  remains ambiguous even after these clarifications, for there are at least two kinds of meaning it could be about (standing meaning and occasion meaning). If it is intended to be about occasion meaning, it must involve a suppressed quantification over contexts (just as it contains a suppressed quantification over languages).
