 In GTS as developed for English in Hintikka &amp; Kulas (1983, 1985), game rules are associated with a great variety of linguistic expressions (cf. Subsect. 2.1). As Hintikka (1990) has stressed, informational independence is a cross-categorical phenomenon: it can occur in connection with expressions of widely different grammatical categories. Hintikka and Sandu (1989) propose several examples from English calculated to show that there is an abundance of instances of informational independence in natural languages. Among examples are wh-questions of the kind discussed above, and the distinction between the de dicto and de re readings of certain English sentences. Hintikka and Sandu suggest that representing such readings in terms of IF logic is more truthful to the syntax of English than the alternative, non-IF representations are.
