Fuzzy sets and fuzzy logic provide (in contrast to classical logic) an effective conceptual framework for dealing with uncertainty and imprecision present in language sentences. Intuitionistic fuzzy sets seem even to be more important in the area due to the fact that they are generalisation of fuzzy sets with another degree of freedom letting us better model uncertainty. In this paper we show a new application (examples) of intuitionistic fuzzy sets - their ability to handling uncertainty in natural language sentences with imprecise predicates and modal operators (necessity "□" and possibility "◊" which have no counterparts in the ordinary fuzzy set theory).
