The interpretation of this formula is a compositional function of the interpretation of phi. Negation is a truth-functional operator, which operates on the truth value of the proposition it is combined with. Modal operators (like necessarily) and tense operators (like ''it has been the case that'') are not truth functional, because their interpretation does not solely depend on the truth value of the formula with which they combine, but also on the possible world or moment of time with respect to which the whole sentence is evaluated.<br /> <br /> === Links ===<br /> <br /> [http://www2.let.uu.nl/UiL-OTS/Lexicon/zoek.pl?lemma=Operator&amp;lemmacode=475 Utrecht Lexicon of Linguistics]<br /> <br /> === References ===<br /> <br /> * Chomsky, N. 1981.
